"DADDY"
I assumed all diesel heaters would be left outside. That would be my plan at least.edit: meant to quote you @sndmn11
I have a FWC Grandby shell that I built out posted on page one. I've built out two of them with diesel heaters, solar, etc.
My brother has a Go Fast Camper on a Raptor and has similar wants to yours. My opinion on your question is that it's kind of difficult with regard to having the diesel fuel for the heater in the truck bed and the fumes. That's no joke. Carefully think through where you would store it at.
One method people do is put the heater in a harbor freight pelican case knock off and set it outside and use ducting to duct the heat in. The hassle of that is that it's another step in set up/tear down and isn't incorporated to "the house".
As for solar, where are you going to mount the lithium battery and controllers? That isn't as hard if you can fabricate, but it's another task. Are they going on the truck bed floor and going to be plugged/unplugged from the camper shell to remove seperately when the camper is removed, or are they going to be mounted inside the shell somehow so it's one unit?
A few of the companies I have been looking at seem to have battery and controller solutions that work in the campers. Some even appear to be modular enough you could mix match brands.
