There are lots of warrantys available for any trailer, just be sure you check for reviews on the internet from owners of the particular company you are considering--lots of horror stories out there. SOME of the warrantys you come across are designed to be hard to make a claim/get reimbursed/go out of business regularly. Fine print is very important.
If you find one you think you like--it should be an "exclusionary" one, that says what is NOT covered.
And, you HAVE to follow the instructions for a claim to the letter, also, many want proof of previous annual maintenance.
Outside of all that, an extended warranty can be a life-saver if the company is a good one. Remember, these are insurance policies and they have to take in more than they pay out to remain in business. You are betting you will need it, they are betting you will not.
Good Sam has one that can be ok, especially if you have the work done at a Camping World--but no Camping World will ever do any serious work on my trailer.
Do your homework, these warrantys are expensive critters...especially if you have to fight to get a claim paid.
