There have been threads on this before on this forum as well as other RV forums.
Essentially, it's just a gimmick in my opinion.
Yes, you are required to do the yearly maintenance at your cost by an authorized dealer in their system but from people I've talked to that have it, the dealerships across the country are not that ubiquitous. In some areas (if you are a full-timer and are moving around a lot), you may (or may not) have a difficult time finding an authorized dealer. You can't do the inspection yourself or have a friend do it and sign the coupon.
Plus, the dealerships that do have it (or are authorized) can charge what they want for that yearly inspection. You have to send in a coupon each year proving that the inspection was performed by an authorized dealer.
The hidden catch from what I've been told is that these dealers are "trained" to suggest additional services during that inspection that may or may not be needed and charge premium prices for them
Some put a lot of pressure on you to do services that are questionable or really not necessary but they are on that fine-line where it's a gray area if it needs to be done or not. Some dealers try to take advantage of those who they feel may not know much about RV systems by suggesting things that scare them into having a service done ...e.g. "wow, you really should flush your water heater or it will explode as we can see a lot of dangerous stuff inside the tank ...we can do it right now for $395 and you can rest easy"
This is not to say that all the dealers will do that. If you have the fortitude to fight off they sales pressure when you bring it in for the inspection, then it may be okay especially if they charge a reasonable price for the inspection. The prices seem to be in that $200 range plus-or-minus $100. It's way too high for what they are inspecting but if you're getting a free lifetime warranty out of it, I suppose it's worth it if you can ward off their high-pressure salesmanship to suggest (or insist) that other services be done that may not be absolutely necessary.
The warranty includes ten (10) items. The first two (brakes and suspension components) I believe are for travel trailers ...somebody showed me their contract once and I seem to remember those two items being left out of the contracts for motorized vehicles. Of course, it will not cover drivetrain or other major chassis components.
Here is the website that will give you a little bit more information:
RV WARRANTY FOREVER®
A short video from one of the dealers:
eta: oh, and notice how one of the items is "Manual Leveling Jacks" ...most Class A motorhomes do not have manual jacks so hydraulic or electric jacks systems do not appear to be covered. We all know that those can be a MAJOR expense when they need fixing. I also don't see slides mentioned so hopefully somebody who has this coverage and owns a motorhome can clarify these two items.
