is it risky buying a travel trailer that is 8 years old

We bought a 15 year old travel trailer this past spring and we're super pleased with it. There's no warranty on it, but the tech spent 3 hours with us showing us everything and how everything was functional. We've used it all summer and everything has been great. I just can't see paying full price for a new RV that we're only going to use in the summers. Even if we need to repair/replace parts, it'll still be cheaper than buying new.
