LP tank must be oriented as designed. If it is a horizontal tank pretty sure it must be horizontal or it will not work. Not that you do not know that.. Just noting for others who may not realize your pics are sideways. Also not sure what box you refer to when you say may mount in box. It can NOT be mounted in camper box. Very dangerous and illegal. Two it must be vented proper. LP sinks therefor vent must be at zero bottom.finally figured out the picture issues...will have a few more to follow.
These pictures are from the box 1 mods including the instant HW heater, the 12.2 gal ASME propane tank, the pump and accumulator and the 30 gallon water tank as it stands right now. Still not sure weather I want to try to mount the tank there or inside the box.
I also got the light bar removed from the top of the cab. Will be installing a cargo roof rack and hook up some led lights to it for some added visibility.
The Instant heater.. You need to insulate it.... Have read several stories of folk who have gone thru 2 or 3 of them in a winter cause they freeze and burst the inner plumbing. Might be better to install that inside the Ambo/camper box. This will also solve the issue with wait time for hot water to get to faucet. Just mount it near the faucet most used. Or loop it as mentioned in next post (#32)
