I have noticed that a lot of the National Forest Service campgrounds state that the sites can only be used by trailers 30 ft and under . A few even have smaller restrictions. I am debating the same thing right now and can't make a decision. Personally I may go for the shorter trailer with the double bunks. My Grandkids, if the are not running around making noise outside ,seem to spend a lot of time laying in bed with thier Ipads and such. I really need to see the trailers I am considering but all the dealers for the ones I want are at least 75- 150 miles from me. Good luck with your search.
