We bought a 32' Keystone Cougar Xlite. We (by we, I mean DH) tow it with a Ram 2500 which has more than enough power. It has one slide, a bedroom with a door for DH and me, queen size bunks for the two boys (11 and 13), a fold out couch and a dining table that makes into a bed for anyone we decide to take with us. We took a 38 day road trip this past summer and loved it. I wouldn't buy longer than 32' because as has been mentioned, it can be hard to find a spot to park them, even in an RV Park.
