The very sad state of affairs today is that the factories are pumping out RVs so fast that QC can't or doesn't do a proper job. They expect the dealers to 'finish' them before sending them off the lot to the buyers.The understatement of the year.
Everytime I contact the guys who sold me my popup, they tell me they have a waiting list for repairs and I am 3 - 5 months out. Really expected them to respond better to someone who purchased from them, but their techs are focused on prepping new trailer sales as opposed to repairing other sales. Dealers see their service techs as simply an arm of their sales department and not a stand alone profit center. Once when I told them I needed the camper for a specific trip, and I knew we had to order parts, they refused to set an appointment till the parts arrived. When the parts arrived, they told me I was out of luck, they couldn't get to my camper for 3 months even though I needed it in 3 weeks.
Sadly, there was not a u-tube video on the repair I needed to do, best I could do was some written instructions for a similar repair and an exploded view. They quoted me 4 hours for an experienced, trained repair tech to do the repair. It took an old man like me 90 minutes to figure it out, crawl out from under the camper 2-3 times and go find the right tool, etc. If I had to do that same repair again, 45 minutes tops. (And with what I know now, probably only need 2, maybe 3 tools.)
If you think it is hard to schedule your truck into the dealer for service, wait till you try to get your camper serviced. And I have spoken to several dealers of campers and motorhomes, none of them gave me any hope that they were any better.
Taking care of the warranty (or other) work after the sale gets to be less important than sales.
The problem today is so bad that those who deliver RVs to dealers have to CAREFULLY document the condition of the RVs they pickup from the factory so they are not held responsible for anything the receiving dealer finds BEFORE they accept it. To do otherwise, the dealer may have an issue getting the factory to approve repairs, even before it is sold.
After that, it is the responsibility of the new owner to 'find' the remaining issues through use so they can be claimed under warranty.
