In March 2006 the wife and I purchased a new pop up tent trailer for a trip out west....we travel through 17 states and Ontario for a distance of 6,500 miles in 30 days. I did extensive research on modifications to the trailer to make life more enjoyable. I found a Pop Up Trailer forum similar to this one for most of my ideas.
We crossed the Continental Divide twice reaching peaks over 11,000 feet. If you have any intentions of traveling with your tent trailer make sure your tow vehicle is up to it and is 100% mechanically sound.
If you have any specific questions I will try to answer them. Here's what we owned back in 2006.
