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

There's always some risk with buying used. I prefer it.. The savings is tremendous. I bought a 95 almost 2 months ago and love it. I just made sure all the walls, floor and ceiling were solid. I went into it with expectation of having to put some money into it above the purchase price. Brakes, tires, batteries, converter, WDH, anti-sway, etc... plus all the accessories and modifications of making it my own. At this point.. I have around $6000 invested and anticipate I will put another maybe another $2000 into it.
