Wouldn't it be nice to setup a guest room outside of the Prevost in only two seconds? Well, it can be done and your budget doesn't have to be more than $69 for one that will sleep two. I'm going to be ordering one of these for my setup.
This is a two person tent that can literally be setup in two seconds and can be taken down in 15-30 seconds!
