The Nash 22h was mentioned above. I own one, and love it.
But... I normally camp solo with my 2 dogs. When a friend and I went on a 2 week desert road trip last year, I got the bed and she slept on the sofa we kept extended into a bed for the entire time. It worked well after stopping at Wal-Mart and buying a cheap foam topper to put on the sofa. It was plenty of space for 2 ladies who come from a backpacking back ground. (Compared to a sleeping bag on the ground covered by a tarp, any RV is a palace.)
Also, I primarily boondock and dry camp - so a trailer that can hold up on dirt roads and is completely self-contained was my priority.
In a nutshell, what kind of camping do you like? If you are towing on good roads to a paved full hook-up site, you will probably do fine with a nicer looking ultra light trailer. If you go to more primitive places, you will want a better built trailer to handle that. I bought my Nash after trashing the suspension on my first trailer - a Keystone Bullet, never meant to leave pavement.
