3rd Party VS Nucamp Extended Warranty

@EllaElla welcome to the forum and I think folks here have had a variety of experiences with extended warranties. I live in a similar situation where I am not particularly close to a dealer, and I purchased my trailer as the second owner.
Since the cost is a significant factor, I think it will boil down to how comfortable you feel with basic adjustments and basic maintenance of the systems in the trailer. One thing working in your favor is that generally the build quality has been higher than most of the industry with NuCamp. We hear much less frequently than with other manufacturers about problems with basic fit and finish on a new trailer.

The maintenance boils down to yearly or every other year tasks which with no prior trailer tech experience, we found to be learnable and doable with help from the Internet and this forum. I was able to learn about basic brake adjustment and wheel bearing maintenance and assessment of the water pump, among others. Understanding the electrical system of the 12 V and the shore power supply is really not very complicated and doesn’t require extensive electrical experience. The biggest task, which is the maintenance of Alde system glycol, we learned from the forum and thus far no issues for 6 years on. The Alde just works each time we need it.

With everything I have read about delays and botched repairs at dealerships, I have elected to stay away unless it was something beyond my knowledge. So far so good.

So if I were buying a new 360 from a dealer pretty far away, as you are, I think I would skip the extended warranty, learn about the basic maintenance procedures, and if there was a major problem during the warranty period, I would just have to take the time to return it to the selling dealer to repair. If you needed to travel to your selling dealer, you would probably cover the cost of travel with what you would not spend on the warranty.
Enjoy your new trailer and feel free to reach out to folks on the forum with questions. I’m sure you’ll get a warm welcome and useful information.
