I have not read through all the responses, but I can say this.... We bought a Keystone Outback 323BH in Oct 2013. We have been full timing in it for 8 months now (2 adults, 2 kids, 1, dof, and 2 cats). About 4 months ago, our black tank broke at the outlet to the waste gate. I had a mobile repairman come out to stop the leak, then I contacted Keystone though their warranty department. They told me to return it to the dealer, but the dealer said it would take 4-8 weeks to repair. I called the mobile repairman and he gave me a quote for parts/labor of $600 on site and all original parts. I contacted Keystone, they approved the repair, but capped at $475... I was OK with that, since the on site service call is $99. I paid for the repair, scanned/emailed the receipt to the service representative and had a check 2 weeks later.... I am very happy with that.
Another one, the selling dealer damaged a bunch of decals when they washed it, after fighting with them for a couple months, I contacted Keystone, sent them pictures, and two weeks later I had a box with replacement of the decals I needed and some nice directions on how to replace them.
So far, I love the quality of this TT. Keystone has come out with a new Outback series (Terrain I think), it does not look as well made....
A lot of times, I think it is the way they are approached which will determine how they help you. I start all my correspondence with Sir/Ma'am and end with Very Respectfully. I have found that will go a very long way in getting needed service.
