    DIY Composite Flatbed Camper Build

    I have the Magnum battery monitor with shunt. I haven't spent a lot of time trying to figure out all the features other than charging and monitoring the battery. There is an amp display that shows amps being used when using the inverter, however when running the 12 volt AC the amps read zero...

    Ran the AC for approx. 6 to 7 hours yesterday on just solar. While compressor ran, voltage would drop to about 12.8, then once temp was reached the fan would continue to run and charge would rise to about 13.4. This was pretty much the pattern throughout a hot humid day with a high of 94...

    Hi Bob, definitely have to get an early start to beat the heat around here!! The compressor has three adjustable speeds which coincides with BTU output. Speed 1, 53A, 7500 BTU. Speed 2, 79A, approx. 11000 BTU. Speed 3, 106A, 15000 BTU. The unit comes from the factory on speed 2. My initial...

    Good news, Bad news, Good news.... The good news is the AC installation is done, well almost, and was fairly easy. I'm very happy with its small size and quality in comparison to the Guchen. The bad news is the compressor is being a little finicky. It works perfectly most of the time, but...

    Getting my ducks in a row for the AC install. Since there are various applications regarding roof thickness and distance from battery, not all hardware is included. Also being imported, the unit is not pre-charged with Freon. Forgot to mention thermostat. As these units are built for robust...

    Changed out the drainage line for the gray tank. The first go around was a blue irrigation hose that I chose for its ability to flex 180 degrees without kinking. With it being a little smaller than my 1 inch drain in the camper, the water would come out a little in the shower drain; probably...

    Anybody understand thermostats??? My Kalori is 12 volts, so I would think I need a 12 volt thermostat? It connects in between a single line that would basically open and close the circuit. Does it really need to be a 12 volt thermostat or will something like this work...

    That's for sure, think YETI will let me borrow their name? :)

    DIY Composite Flatbed Camper Build

    Finally found "THE 12 VOLT AC". After looking and studying for more than a year at various types of AC suitable for an overland camper, not to mention making 2 purchases, I have what I've been searching for. As mentioned before my criteria was efficiency, light weight, reasonable cost, and...

    Took off for a quick overnighter to the NC mountains. "Maiden Voyage" I was most impressed with the electrical system. The REDARC, Stark Lithium batteries, and Magnum inverter provided plenty of power for our needs. We arrived at our campsite for our evening meal, so we had full charge...

    I've been having a problem with the water pump pulsating. It is a Shurflo by-pass pump that does not need an accumulator. I checked all the lines for tight fittings and made sure there was no air too. None of this helped. In the operation manual it talks about a by-pass adjustment that should...

    DIY Composite Flatbed Camper Build

    Preliminary observations with the REDARC and drop in Stark batteries using only solar "400watts"; When I kill the batteries to the camper and just allow solar charging, I've seen a max charge of 14.1. As soon as I turn the switch back on with no inverter activated just 12v units (not on, just...

    Redarc1240D vs Lifepo4 ?

    This is my understanding as well. Although the lithium is "branded" a drop in replacement, it has different chemistry and charging profile. I'll bow out of this for now and post results on my build thread :)

    Redarc1240D vs Lifepo4 ?

    I too was using an SI-ACR "https://www.bluesea.com/products/7610/SI-ACR_Automatic_Charging_Relay_-_12_24V_DC_120A" but was concerned about the possibility of frying my trucks electrics when battery banks were combined. The REDARC is a one way street from truck to coach battery and also serves...

    Redarc1240D vs Lifepo4 ?

    I've just begun testing the REDARC with Stark Lithium batteries. My observation so far; if I kill the batteries to the coach and just allow solar charging, I've seen a max charge of 14.1. As soon as I turn the switch back on with no inverter activated just 12v units such as water pump, TV...

    Went with vinyl for the graphics- $60.00. The foam cushion definitely created a tighter seal between cab and camper. Wind noise level was less at highway speed. Probably due to the foam boot and wedge shape of the camper. As for Air conditioning, I feel like I'm flip flopping all over the...

    Awning is up and insulated boot to cab is made. Not sure how well this will work yet, hope to get it loaded up again and do some more testing next week. I may have found the perfect AC. After the Chinese/Alibaba "still ongoing" experience, I thought I found a 12 volt roof unit. "Thought" is...

    Awning install. Went with a dometic A&E 9500 Case awning. Self supporting and a decent price. This is a fairly easy install. Once again the aluminum L channel have proven to be a strong attachment point using rivets, stainless lag bolts, and SIKA 252 to secure the mounting plate. Give it a...
