We have a KZ 16RBT hybrid and we tow it with a V6 Toyota Tacoma. We actually could have towed a bigger unit, but parking is an issue here at our house so we purposely went smaller. We love the Hybrid and how easy it is to tow, back up, and set up and take down. The advantage to the larger hybrid would be a better closet/pantry and more storage, but the unit we have beats the heck out of tent camping! http://www.kz-rv.com/products/sportsmen-classic-travel-trailers/16RBT.html
The Spree Escape is a bit more upscale version of the same basic model.
the GVWR of the 16RBT is 2,800 lbs. The 18RBT is 3,500 lbs. the 20RBT is 4,500 lbs.
