Lots of good things to say about Keystone quality control. I just traded in my 2014 Heartland Bighorn 3570RL on the 2015 Keystone Raptor 425TS. The Bighorn was to be our last full time unit, then a winter in the AZ desert watching all the people play on their toys, convinced us we needed a toy hauler. Although the bighorn is supposedly a "luxury" top end unit...not so. I found the quality in material and workmanship very lacking. The 425TS on the other hand, is a pleasant surprise. On a 1-10 the bighorn is a 6, the keystone is a 9. The few small issues will be an easy fix. Going out to the Utah west desert today for a shakedown of the 425. I'll keep u posted on how it runs out.
