Man Im no “van-lifer” but I I’ve lived outside for a time “tanker in the corps”, anyway the shower situation; I get a 1-2 gallon pump sprayer and rig up a sink sprayer to the end…then get one of those cheap “shitter” tents, the pop up kind there like $20 and use that as your shower…just boil a pot of water “a big propane tank is like $20 and will last a while” oh yeah…you’ll need a camp stove, propane kind “check goodwill”and one of these, or this is you want to just run off a 20lb tank. Hope this helps you out, it will cost a little up front, but in the long run it’ll save you money, and you’ll be able to cook healthier food, man is not meant to live off ramen noddles alone ;) good luck to you! Stay safe out there
