When we went camping during this past summer we rented a Pop-Up Tent Trailer from them. If you are small perosn like me or my kids than the trailer that we rented is the perfect size to sleep in, but if you are a big person like my husband that you would want to go with a bigger size trailer. The trailer that we rented wnet back cleaner than when we picked it up and not only that my husband was ready to rip off the door the first day becasue we were not on a flat surface for the first couple of nights and the frame of the trailer was so tweaked when he had it right for the door to close good. But all in all I wouldnt' mind renting one again becasue it sure beats sleeping on a hard ground in a actual tent. And you can actually stand up while changing your clothes.
