IDK man, although being a one off, would be willing to bet that anything similar produced in any kind of production /“professional” fashion probably wouldn’t look much different than what you did.

Your encouragement means a lot - thank you. While I appreciate the vote of confidence, I know there are skilled professionals out there who would spot plenty of rough edges in what I've built. I approached this as a personal challenge with what I had on hand: basic tools, limited experience, and everything done right in my driveway using just a single extension cord. It wasn't perfect by any stretch, but it was a rewarding hands-on project, and I'm genuinely glad others followed along and shared in the journey. If it inspires anyone to try something similar (or do it better!), that's more than enough for me.

Have you measured temperature inside the box when heat was in use? It would be interesting to see how hot it gets and the longevity of the equipment inside. I assume one fan is in a push setup and the other is in a pull setup?

Yes, I monitor the internal temperature of the Zarges K470 enclosure (what I'm calling the MES-K470 setup) using a probe tied into an Inkbird ITC-1000 controller. That feeds a compact Noctua NA-FC1 fan controller, which handles two Noctua NF-A12x25 PWM fans in a push-pull arrangement - one pushing cool air in, the other pulling warm air out.

I set the fans to kick on at 90°F and shut off once it drops to 80°F. To size the system, I ran through various load scenarios (mixing solar charge controller output, DC-DC charging, inverter draw, diesel heater operation, etc.) in both hot and cold ambient conditions, then designed around a conservative worst-case estimate. With the fans at full PWM speed, they move enough air to refresh the enclosure's internal volume dozens of times per minute - plenty of margin for the loads I run.

As one example taken moments ago: with the diesel heater on low, the solar charge controller active, and the inverter running, the internal temp stabilized around 85.2°F (battery at 97.6% SoC, solar input just trickling at ~3W in float mode). I'm pleased with how it performs under real use, though I fully recognize the setup is more elaborate than most people would need - this was largely an engineering experiment and learning exercise for me.

If you're building something similar, I'd be happy to share more details on the calculations or component choices; happy to help anyone avoid some of the trial-and-error I went through. Thanks again for engaging!

I completely forgot you included a temp controller for the fans. I should have known better. I think you considered pretty much every situation to ensure success.

No I am not building anything at the moment. But was watching just to continue learning. Maybe this summer when I start/finish the inside of my camper.
 
I selected the Luverne Grip Step 7" x 98" aluminum wheel-to-wheel running boards after a thorough search for options suited to a regular cab with long bed. Full-length boards proved scarce - most covered only the cab area - while I required frame-mounted brackets exclusively, avoiding any rocker panel attachment. I also prioritized a flat platform with expanded metal tread surface for superior traction and debris shedding in demanding environments. These Luverne steps uniquely met all criteria, making them the clear choice for my build.

The 7-inch-wide stepping surface ensures safe, comfortable access and egress. The open expanded metal treads effectively shed dirt, snow, and debris from boots, and the powder-coated aluminum construction delivers strength, low weight, and complete rust resistance.

As installation neared completion, I briefly considered omitting the end caps. Upon reflection, their smooth, rounded profile eliminates sharp edges and neatly conceals what would otherwise be an exposed, unfinished end - enhancing both safety and aesthetics.
RC 26-027.jpg

Two standout features deserve mention. First, the expanded metal tread pattern matches that of my camper entry step stand, creating uniform footing and boosting overall safety. Second, the running boards mount at precisely the same height as the top step of my stand. This eliminates the need to haul the stand when securing or releasing the front four roof latches on my Four Wheel Camper - a small but meaningful efficiency gain. In freezing conditions (teens or twenties), manipulating cold metal saps hand warmth quickly, and gloves compromise the dexterity needed for those stubborn latches - making this integration a genuine time- and comfort-saver.

This is the front mounting bracket on the driver's side. The powder-coated brackets employ stainless steel fasteners and exhibit high-quality fabrication.

The instructions were thorough and illustrated, but contained a notable gap: body mount bolts are to be discarded without reuse, yet no guidance addresses the substantial factory washers (~4" OD). Luverne tech support offered no explanation for their function and insisted on non-reuse per the manual. Observing the kit's bolts were 10 mm longer each, I applied basic load-distribution logic: the washers must remain to spread force evenly over the rubber body bushings. This critical detail appears to have been omitted during the transition from design to documentation.

Here is the rear cab bracket on the driver's side. On a crew cab, an additional body mount and bracket would appear between front and rear; for my standard cab, only two per side are required. Vertical adjustment capability here is a smart, practical touch.
RC 26-031.jpg

Close inspection of the load reaction studs reveals how they preload the brackets against the frame, channeling step loads directly into the chassis rails. This is a solidly engineered approach with broad adjustment capability that impressed me.

The rearmost bracket attaches to the side of the front eye bracket for the rear leaf spring on my one-ton truck. It uses a 30 mm head bolt torqued to 350 ft-lbs (my son handled the final torque). Horizontal adjustment is available if needed. In summary, the frame brackets reflect thoughtful, heavy-duty engineering with practical adjustability.

Tonight I camp in the Croatan National Forest where it's been in the 20s the past few nights, the crisp air sharpening every rustle in the underbrush. Named for the Croatoan tribe who once called this region home, the forest guards the echoes of the enigmatic Lost Colony - those 115 English souls who disappeared from Roanoke Island in the late 1580s, leaving behind a single carved word: "CROATOAN." Many believe they blended into the local Native communities hereabouts, their fate a mystery that still draws explorers like me to these shadowy pocosins and tidal edges, searching for traces in the silence.

As I continue my slow trek south, I paused in New Bern, North Carolina, to visit an old friend and explore the area. Founded in 1710 by Swiss settlers, it's the "daughter city" of Bern, Switzerland. The downtown exudes rich colonial history the moment you step onto its streets - quaint restaurants, cafes, art galleries, and antique shops abound. We toured the magnificent Tryon Palace, its surrounding museums, impressive architecture, and stunning gardens. Full-time travel keeps delivering these surprises: places you've never heard of that make you think, "Why didn't I come here years ago?"
RC 26-036.jpg

We devoted a full day to Tryon Palace and its grounds. The highlight was a one-hour guided tour led by docents in period dress who brought the place to life. It reminded me of Colonial Williamsburg - similar feel, but on a much more manageable scale (Williamsburg needs 3–5 days). In the upper-left photo, you'll see the handsome horse stalls; I have a weakness for fine old wood, brick, and craftsmanship. The other three shots show interior details, where our guide did an excellent job explaining daily life for the household and servants.

Built 1767–1770, Tryon Palace stood as North Carolina's first fixed colonial capital and home to Royal Governor William Tryon - under the reign of George III, a king whose House of Hanover was unequivocally German in origin. The dynasty originated in Hanover, Germany, and ascended the British throne in 1714 with George I, a German elector chosen over closer Catholic heirs. This German royal line governed Britain (and its colonies) for nearly two centuries, with George III himself holding dual roles as British sovereign and ruler of the German Electorate of Hanover. Tryon departed for New York in 1771; Josiah Martin followed until his 1775 escape at revolution's outbreak. Patriots then used the Palace as the new state's capitol, hosting foundational General Assembly meetings. The monarchy's deep German ancestry persisted; only in 1917 did King George V rename the house from Saxe-Coburg and Gotha (another German branch) to Windsor to quell wartime anti-German sentiment.

When Governor Martin fled in 1775, he left behind most of his fine furniture. The revolutionaries auctioned it off, using proceeds to fund the war effort. Many pieces ended up with local families. Today, a few originals from Martin's household - along with items tied to first state governor Richard Caswell - have been returned or replicated in their proper places. On tour, you can spot them if you know what to look for; it's a tangible link to that chaotic transition.

Tryon Palace holds a strong collection of 18th- and 19th-century furniture - mostly English, with American examples from New England, Mid-Atlantic, and select North Carolina pieces (heavy on New Bern/Craven County). The American items relate mainly to Josiah Martin's time (1771–1775). A former New York-based officer who married his first-cousin, he included pieces like a Chippendale mahogany desk, pierced-back chair, and large eight-legged dining table - possibly auctioned in 1777 and acquired by Caswell.

The grand staircase was a showpiece - crafted from costly West Indian mahogany that ran 600 pounds (24–30 times an average North Carolinian's annual wage). It highlights the stark class divide: this ornate "canal lever" design (a sophisticated engineering feature) welcomed guests and displayed power, while servants used hidden, steep "lesser stairs." The design literally separated worlds; the social engineering is as evident as the joinery.

This view from a second-floor window shows the well-kept neighborhood - fresh paint, tidy yards, classic homes in fine shape. It was cold and rainy, but we made the most of it and enjoyed ourselves. My bird-savvy friend noticed external bird-themed architecture, which launched us into a lengthy talk about homing pigeons, doves, herons, falconry, and related topics. Always good to have company with specialized knowledge.

The Kitchen Office (first floor: kitchen, scullery, wash house, secretary workspace; second: servants' chambers and laundry) was cutting-edge for 1770 - modern conveniences of the day. It still feels primitive now, but the sights, sounds, and smells of 18th-century cooking are vivid. Daily period dishes use garden produce. The clock jack and weight stood out - similarities to the micro-mechanical timepieces I collect from Switzerland and Germany. Solid engineering for its era.

The North Carolina History Center offers rotating exhibits, interactive displays, waterfront dining, and shopping - aimed at freshening the historic experience. It covers coastal formation to regional shaping. In my view, though, it's a misallocation of funds. After days of classic craftsmanship and quiet elegance, I found it disappointing: stark modern exterior, disjointed interior design, and heavy emphasis on environmental warnings and certain groups' contributions - while downplaying others. The bright colors and constant music felt overwhelming. I shared my thoughts politely on the way out - gentlemanly disagreement is still possible.

Let's close with Tryon’s Latham Garden; a classic formal English-style parterre - flowers, clipped hedges, pathways - evoking 18th-century Britain. Overall, 16+ acres in colonial revival design (1950s, Morley Jeffers Williams) include patterned formal gardens, heirloom blends, a kitchen garden with heritage herbs/vegetables, pollinator-friendly natural areas, and three period houses with distinct themes: camellia-focused lawn, white-themed Georgian, and Southern-style Victorian. A peaceful, well-executed landscape.
