I watch the video from the above post. I must say he presents a pretty bleak picture of the RV industry. Unfortunately there is a lot of Truth in what he says. I don't think it can be emphasized enough that purchasing an RV is not the equivalent of purchasing an automobile. The standards are completely different.
Based upon what he presents in the video, no one would ever buy an RV. But the fact is we keep buying them but we also are aware of the expectations when we purchase them. It still goes without saying that there is a large amount of work that has to be done on an RV yourself. Some things like drawers falling off loose screws or a hinge that might need tightening down is all stuff that anyone can handle them self with a screwdriver or a hammer. When it comes to something major like, a plumbing repair, then warranty should cover those type of issues. But there's also the problem of user abuse. If it's determined that the user has indeed done something incorrect with the camper, then no warranty will ever cover that. And unlike a car it camper is a much more fragile device. The electronics is extremely complicated. There's water Plumbing involved. There's a drain system involved. There is a c electricity involved. There's DC electricity involved. There's all kinds of appliances. There's all kinds of electronics. There's all kinds of materials in the structure, roof, ceiling, walls, floor, countertops, you name it.
Then add to the fact that you're taking a home putting wheels on it and driving it Down a Bumpy Road at 65 to 85 miles per hour, the equivalent of a hurricane, and tornado, all in one, it's a wonder that they hold together at all.
Your absolute best line to protection is to be fully aware of what you're purchasing before you buy it. And then to have a little bit of mechanical ability behind you. It pays to have a few good tools. And somewhere where you can actually work on the camper occasionally. No one ever said that RV ownership is cheap. RV ownership is one of the most expensive Hobbies you'll get into, next to owning a boat. There again your best line of defense is to learn to do things yourself.
