I'm scheduled to pick up my new 2015 3160 later this month. I'm curious, did you have any major issues? 30 items seems like a lot to me. My last camper only had a few issues and I put about 12,000 miles on it during the warranty period.
The issues are not crippling to the trailer. They are fit and finish mostly. They include a dripping faucet, relcliner that won't recline, convection oven that won't heat up beyond 250 degrees [replaced and will be installed next week], screws (sharp points) protruding into the utility center, bad shade on the kitchen light, weatherstripping issues (a few around the trailer, but no leaks),torn carpet in the livingroom slide, window shade adjustments (some won't go all the way up, one is not correctly fastened to the wall), etc. No big deal but things that should have been caught at the factory or PDI.
Nothing is serious enough to cause us to skip a trip this summer. Now that we are done, the dealer will fix them up. Heartland customer service is great and has been a big help. I don't belong to the club that thinks it is normal to have warranty work on a trailer. But I do recognize that Heartland is no worse than any other manufacturer. Quality assurance is just something the industry doesn't want to pay for. If they get foreign competition that delivers problem-free trailers, things will change quickly.
Don't get me wrong. We love our Bighorn. Heartland has put in the very best components and the engineering is great. There are always outlets where we want them and we love the floor plan. It wasn't an inconvenience to go through the season with these issues. I have confidence in Heartland and my dealer to correct them. My advice to you is to take a lot of time on the walkthrough and make sure the dealer records any issues. If you have the time, make them fix everything you find before it leaves the lot. However, like most of the others here, I have complete confidence that Heartland customer service will make sure that anything that you do find after delivery will be fixed and fixed right.
