i dont have their coverage, but ive looked into it - i saw no specifics that indicated the wouldnt cover our type of equipment.
also look at GOOD SAM (aka camping world).
I havent done extended warranty - while i considered it, generally the deductibles are too high and ive not needed it....i had to have some spring bushings in the rear replaced and while it wasnt w/out some (wallet) pain it really wasnt that expensive ($1000) considering the amount of work & time that the shop had into the job.
I added roadside assistance via BlueSky Insurance - it covers towing and road side tire changes....about all we need really.
