I use my Ranger pickup with a topper to sleep in. Just put an air mattress down and a sleeping bag. I usually take an extra so that I do not have to unpack my pack. If I am moving around I usually just go to a restaurant or convenience store to eat. I can cook in the back if the weather is good. Ranger 4 cyl straight stick gets about 25 MPG if I keep the speed below 65. I have a state park permit so I just go into a state park (the trick is to just drive in like you belong there) to take a shower. I have actually paid the camping fee a few times, depending on the time I get back out to the trailhead.
