I think you did key on one thing and that is making it ready for resale when the time comes. You might not want a stove or microwave but prospective owners might. I'd at least think about trying to design it around a standard build. Pre-wire for solar, stereo and TV. Have the space and the power outlet for a microwave & even if you don't want it, the space can be used as a cabinet. Look how hard it would be to add anything to the build after it's completed and have it done during the build if it makes sense money wise. There are a lot of items that can easily be added on the cheap if a new owner wants to, so don't worry about that stuff and build it how you want.
Concerning the diesel cook top, I'd research how well it works at altitude. As far as heat, I can't say if it will produce enough heat for sitting in a ski resort parking lot. Badger put a Wallas in their vehicle. They complained about flame out at high altitude but overall seem happy with it. What I liked about the Wallas is it's also designed to help heat the cab where other are not IIRC. I just couldn't see spending that kind of money on a cook top. My Smev serves me well and they do add moisture to the air when working but it's not bad. I try to cook outside as much as possible but that is a good idea anyway while in bear zones.
On the duel rear wheels, I had those on my work truck and they are not the best for off road travel plus if you ever get a big rock stuck between them, it can be a PITA to get out. A wider single seems a better choice for trail driving.
Enjoy the build out process.
