I had a 2003 Taurus station wagon in 2008, which I sold to my mom after about 8 months. While I could lay down inside, it was cramped as all get out and had no handle inside the back hatch due to having a rear facing seat meant for kids (so they can't open it). So I had to climb in the rear side door and shimmey around. It was not nice at all really. If it had an inside handle on the hatch, I wouldn't have minded it as much. Plus I had almost no place to put anything since the cargo area was supposed to be for sleeping. it required flattening out the back seats (they fold forward). So I had a bed and almost no storage except the front passenger seat area. Okay for a week trip but that's about it.<br><br>If I were ever to go with car living, it would be with a 90s Chevy Caprice/Buick Roadmaster station wagon, the last of the true full size station wagons. Some have the LT1 like Corvettes and they can tow close to 5,000lbs safely. They get about the same mpg as that whimpy v6 Taurus I had that is a much smaller car and can only tow 1000lbs or so. But at 23-24mpg, you may as well have a mini van for more headroom and storage.<br><br>It should be noted I have slept in compact sedans before. On road trips as a kid, my mom and I would sleep in her 91 corolla. We laid the bucket seats back and slept that way, but I found it nearly unbearable since I like to sleep in any number of positions. <br><br>Last year I went car camping and I didn't bring enough padding for the ground in my tent. I had to sleep in the back seat of my 93 Escort and I was cramped and uncomfortable but it beat trying to sleep on the hard ground like I did for the first night.
