    Ski Bum Truck V2.0, F450 Rough Road RV

    I haven't calibrated mine yet, but "calibrate" is really just turning up the combustion fan speed so that the thing runs leaner. You should be able to do that with the rheostat type controller if it plugs into yours. No idea if it can or does. Supposedly they are fine up to about 5k feet of...

    Ski Bum Truck V2.0, F450 Rough Road RV

    Im only in page 10 of this build, but I thought this might help with the Webasto altitude decision. https://faroutride.com/webasto-espar-high-altitudes/

    Custom truck camper, let's talk materials

    1" x 1" vs 1" x 1.5" tubing - My understanding is that the strength of the tubing relates to tube size, and the durability relates to wall thickness. If going smaller, size up in wall thickness. I would rather go with the larger dimensional tubing with the thicker walls spaced further apart...

    high output solar panels?

    On my Airstream I had 520 watts nominal of solar. We were at altitude camping up by Purgatory near Durango. A big storm rolled through, followed by sun. For about 5 minutes my panels were putting out just over 630 watts. Investigation revealed that all of the water drops beaded up on the...

    high output solar panels?

    I agree about hitting them on tree branches, etc. I have one on the roof of my Sprinter, and have to be careful about that. On the sides could be worse. Another idea that comes to mind is having them stacked on the roof like an top and bottom drawer. Same concept as far as the panel serving...

    Hydronics System Questions

    I would caution against any stone/cement products. The reason they suggest them is that the stone is heated and creates additional thermal mass. That is great for a non-dynamic situation. In a rig that will see movement/vibrations/flexing, it will not hold up, and it will add a lot of...

    Forest Sevice Hotshot Crew Truck.

    Not sure about topping up to 73, then bleeding it down by driving it. It would take about 45 minutes to an hour of driving to do so. There is info on the tank decal about only going to 70 gal. That and the Father in law was/is a truck driver. He was telling me to make sure and leave...

    Medium Duty Ambulance FAQ (Freightliner, International, GMC, Chev)

    I am guessing that I would need to measure the distance between the front axles to the rim interface, then do the same for the back. Cut the difference in 1/2, and look for that offset? Either that, or I further need to account for the wheel flange thickness, and divide that in half too, then...

    Medium Duty Ambulance FAQ (Freightliner, International, GMC, Chev)

    Just curious. The 29378SP you mentioned lists "Trailer or Drive Use Only" on their site. Are you using it on the front anyway? Link: https://buytruckwheels.com/collections/accuride-aluminum-super-singles/products/22-5x12-25-hub-pilot-zero-offset-accuride-standard-polish-aluminum

    Custom truck camper, let's talk materials

    Voids in structures. Just thinking out loud here, but a hollow tube is an air gap, in a similar way to the air gap between window panes. Curious about the necessity to fill those voids. With a tube steel frame, one could also weld eyelet lifts on top of the camper for overhead lifting. Not...

    Forest Sevice Hotshot Crew Truck.

    Well there is that. It is what happens when you park it on a serious downhill and don't cool it off enough by idling for a few minutes so as not to piss of your friends hoyty-toyty neighbors. Do you have to yell "on belay" each time you walk down to check the mailbox?

    Hydronics System Questions

    I do not have this, but did some investigating for a different build where it did not pan out. The easiest way to do this is to create a sub floor, and run the hydronic tubes under the entire floor area. -Pick the sub-floor material that you want for your interior space. I will use 3/4" ply...

    Custom truck camper, let's talk materials

    A few comments about the structure and material. Using larger steel beams spaced further apart to gain the same strength with additional wall thickness for insulation and fewer beams for fewer thermal bridges vs aluminum. Maybe 1.5" x 1" or 1.5" x 1.5". OR 1.5" square for all the main...

    Forest Sevice Hotshot Crew Truck.

    I don't have a hard number. This one has a single 73 gallon tank, and the recommend only putting in 70 gallons due to expansion. Each time you hit a fuel stop the pump stops at either $75 or $100, so I didn't fully top up until I hit an actual high volume truck stop pump. $148 later... Then...

    Forest Sevice Hotshot Crew Truck.

    The exterior skin is aluminum. I know because the magnetic tag for the test drive would not stick to it. Not sure about the interior skin, or frame. I believe the frame is actually steel though. I'll hit it with a magnet the next time I am out there to be sure. There will be quite a bit of...

    Forest Sevice Hotshot Crew Truck.

    Oh, it happened. 1000 miles of diesel for two vehicles, and my wallet is lighter by a bit. I'll try to find the ECM for the tranny, and get the codes. Thanks for the beta. BTW, rear box interior volume on this one: Height 6' 2.5", length 14" 0", width 7' 8" or 7' 10" (can't quite remember...

    high output solar panels?

    1 - Ever seen the steel shelf supports that are used to make a flip up section at the end of a counter or other location? Build a bigger version of that and mount some panels on it so that they can be flipped up once on site. Put them at roof height, and buy panels big enough that they will...

    Diesel or Induction or propane cook top

    I have used origio alcohol stoves (1 build), propane stoves (2 builds), induction cook tops (1 build), but not diesel cook tops. I am currently planning out my next build, and my decision will be between propane and induction. The wife wants the use of an oven (not microwave), so that is the...

    USFS Crew Buggy- DIESEL

    I just picked one of these up, and can clarify a few of the items mentioned in this string. Some of the trucks bodies (rear passenger compartment) are manufactured by a company out of Texas that uses prison labor to make assembly components. The same company makes license plates (no really)...

    Forest Sevice Hotshot Crew Truck.

    Just picked up one of these that was used by the Sacramento district in New Mexico. Trying to find any maintenance history, manuals, FS operator manuals, etc. so I know some of the idiosyncrasies about this vehicle. Perhaps even hook up with a former or current operator for a question/answer...
