We bought used first and got a great deal but the TT didn't exactly fit our "wants" for comfort. We traded it for a new 5th wheel (in my signature) and couldn't be happier. We have had it since April and have taken many trips. Other than tightening a thing or two that came loose on the first trip, our trips have been fairly flawless. Many on here say that the original owner on a new camper has to work all the bugs out so buying used is the way to go. We fortunately haven't had any bugs so far to work out. We got lucky, I guess. Whatever you decide, just make sure you do a thorough PDI before taking delivery. Anything that doesn't meet your 100% satisfaction that day should be addressed and fixed before acceptance. I have been told that it is very hard to get things worked on after the camper leaves the lot...thankfully, I haven't needed to find out first hand. Good luck and happy camping!
