I have only discovered the van life may be less than 10 months ago when I met one of my friend in Washington state on vacation. since then I became interested in van life.
I surely will have questions regarding builds, designs, electric/solar system.
yes, i am leaning more toward camper stoves at this point. same idea as you, can use them inside or outside.
i am considering nixing the idea of having a fixed sink inside but some kind of portable table that i can use inside/outside. maybe a swing table? that’s connected to fresh and grey water tank somewhere.
Lot’s of camping tables available, the aluminum top ones work the best to put a stove on.
I have 7 gallon gray water tank, that I dump water from my dishpan into using a funnel, and a hand pump to pump my shower water into it. In cities I’ll usually dump it down a drain at a DIY carwash. When boondocking I use it to put out my campfire, or dump it away from my campsite.
While maybe not as convenient as plumbing, I have no plumbing to freeze or leak. I also don’t need to find dump stations.
