Maybe...
I would look for a company other than the what the dealer is pushing and compare apples to apples. My wife got it originally, but after careful review we canceled it. On our small trailer I would have had to replace every major appliance twice for the warranty to even come close to paying for itself (one advantage of buying a small cheap trailer
) Also read the terms of the warranty, where work has to be performed, etc. In most cases IMHO they aren't worth the money, especially if you can do your own work. If you use the trailer at all, most of your problems will show up in the first year.
