I’ve used the Luxury RV in my deathmobile game, and can recommend it for folks who aren’t serious hoarders. It’s slim enough to squeeze through a lot of places that a larger vehicle couldn’t. With a composite ram up front, and the windows all reinforced, I rarely have to do serious repairs.
I haven’t installed all the extra tile-eating tools like the welding rig and stuff, opting to use a UPS charger station on one tile, full of UPS-modded tools instead. Space is still a little tight, even after replacing a lot of aisle with cargo carriers (which has the disadvantage that it takes a while to move over) but I get by just fine. I just have to prioritize whether to take some loot or leave it, because I can’t possibly carry everything. Stuff that’s easy to acquire gets left behind.
It’s solar powered most of the year, but guzzles diesel like there’s no tomorrow in winter.
