There’s one based on a Chevy Express that I see around town regularly, painted blue that the owner appears to be living in. Could refit one for camping/rv duty
In 1999 My wife and I accompanied by our West Hiland terreir went on an8600 mile cross country trip in a 92 Plymouth Voyager ait all except the front seats removed. We took Aur Mattresses, camping and cooking gear, coolers and water jugs, plus suitcases of clothes for when we stayed in motels.We camped in State parks in WI, Forest service campsites, Grand Teton and Yellowstone, Mount Ranier, Crater Lake, Yosemite , Zion, Bryce Canyon, and Arches.
The van performed flawlessly, we did not buy it for the trip , it was our daily driver. It also hauledsix adults out to dinner once a month, something none of their cars would do. building materials and my large snowblower or small riding tractor to my father in law’s house or our church until they got their own mower.
Most versatile vechicle I ever owned. Liked it so much I replaced it with a 2002 or 2003 Town and Country. Don;t remember which year.
Occasionally drove one of these, 4X4, always wanted one for deer hunting in Utah.
My Ford Station Wagon emergencyehicle with thin mattress in back was perfect!
After a long distance emergent bloodelivery in the middle of the night, we were dead tired.
Returning in a heavy rainstorm, we finally got to a Rest Area and were warm and cozy and secure.
Since then, our Lexæ RX350s do not have the space to stretch out.
But if parked up a good slope, the reclined front seats are almost horizontal and allow productive sleep.
In the 60s either a “Popular Mechanix” or car oriented magazine wanted to do a cross country trip, keeping to legal speed limits, in the shortest amount of time. Two drivers, they chose a full size Pontiac wagon so they could alternate driving and sleeping, stopping only for gas and fast-food.
The lowest cost option here is likely a minivan. There was a guy at the bar in my younger days who hung out and slept in his van after the bar closed down. I don’t remember the model but it was some Mazda body on frame with a regular 4WD transfer case and a manual transmission. I think he basically said it was the same thing as a Ford Ranger from that era but just in van form.
Humidity is a thing for sure and especially bad on colder nights. I usually camp in tents but have found that running a small battery fan can really help with this. It doesn’t have to be pointed at you but helps circulate the air out of the tent and greatly reduces condensation. I actually found the fan laying in the middle of the road while leaving a campground once so guess someone left it on top of their car or trailer unsecured. It contains a small battery but has a USB port and you can run them as long as you want with a charge pack/power bank attached.
Any mini van is best, you can remove or store the rear seats and put a twin sized mattress in it.
