I have a 04 Keystone Challenger. It is a midline trailer and in 10 years I replaced a converter the 2nd year, had a small delam spot that got fix but now is visible where it was repaired. Some loose trim and a overhead cabinet that almost let loose that I caught and repaired, new leaf springs and shackles new landing gear leg. I am thankful most stuff was just wear and tear items over the years considering right after I bought my trailer I heard in the news that 1/3 of Keystone work force was fired for drugs or alcohol. I am glad it still rolls down the street. I would probably buy another. Just do a good walk through on the trailer before it leaves the lot.
