Had a travel trailer, and got rid of it, my family and I camp in a Cabelas Guide series now, 10x20 - great cabin tent, but a little too much when I do a solo fishing trip. I also have a 8x16 that my son and I use sometimes. But I have been thinking about, on and off over the last couple years now, buying or building one of those teardrop trailers. they can be built on a 4x8 harbor freight or similar trailer and are just about a perfect size for one, or two if your cozy. I figured I could beef up the suspension and hook it to the back of the jeep and take it just about anywhere.
Just another thought for solo or two person camping, and you could build in a little heater if you wanted.
The one I saw that made me start thinking about this was a home built called a weekender - a couple sheets of plywood, a little waterproofing and it was good to go.
here is a link or two if your interested
