We picked up the Camping World extended warranty. I cannot recommend this or any other extended warranty. All are basically an insurance policy. Usually a deductible involved with any claim. Further there are so many loopholes and disclaimers they almost never have to pay for repairs. One of the biggest "gotchas" is having to have documented proof of annual preventative maintenance.
First year issues are covered by the trailer manufacturer. Other multi-year warranties on the some of the appliances and roof are covered by the individual manufacturers of those products.
In the end, you'd be better off taking the money you'd spend on the extended plan, putting it in the bank and using it as needed for any repairs.
