Thanks for the information.
A friend of mine has an Explorer with the blacked out windows and he works some 30 miles from where he lives. If he has to work over he camps in it at work. Has a beach towel strung up across the front seats like you are talking about. Uses clothes line tied to hooks he installed. He hangs the towel with wood clothes pins he buys at a Dollar Tree store.
If you were going to boondock or camp in campgrounds you may be able to get wrap around windshield & front window covers like they use on RV's. Thus your need of the towel for a curtain would be null and you'd have the feeling of more room.
If you are going to be boondocking or rough camping in the wilderness, they make these toilet & shower tents.
A lot of Van Dwellers purchase small agriculture pump sprayers and paint them dull black so they can be filled with water, set in sun (solar) to heat the water and "instant shower system". The small chemical toilets
can be had for around $50 bucks. They are plastic so that if you take a shower where it is setting it won't harm the toilet.
Here is a garden pump sprayer with a kitchen sink sprinkler adapted to it to make a shower. Painted black
it will heat the water inside when allowed to sit in the sun for awhile.
Just wet yourself down, lather up in soap, and hose yourself off. Viola.
But if you are just traveling there are any of several National Gym's you could become a member of and have
24/7 access. Even sleep on their parking lot at night. Planet fitness comes to mind...nice places with showers, bathrooms, lounges where you could watch TV, use your lap top while recharging it and the WIFI is just free to use there. Low monthly membership cost.
I'm willing to bet that you could do a Google search for your camp stove and find information on it. Possibly a copy of the original manual to read and learn how to operate it. I know Walmart has their own "white gas" which is cheaper than the Coleman brand.
If you need light at night, consider those little solar charged LED sidewalk marker lights. Get a few of them at the Dollar store and set them out during the daytime to charge. Then by night bring them inside for lighting your interior.
You could get a 5 X 7 plastic tarp and rig it to the side of your Explorer. If yours has a roof rack you could lash the tarp to an extension tent pole and then attach that to the roof rack with clamps. Then with poles
set up the outer edges and rig them with clothesline rope tied to tent pegs. You would then have an awning
where you could set up a folding camp chair. This would give you some living room outside the rig.

All of this would be minimal of course but it could get you free of insane rent and having to live with others in cramped quarters. You may come to enjoy the freedom and flexibility of coming and going whenever you wish.
