We initially bought the extended warranty based on the verbal description by our sales person. My biggest concern was warranty against delamination, issues with the slides and issues with the leveling system. Accessories and appliances in the rig are not that expensive, other then the fridge and they have their own warranties......of course all our concerns will be covered.
As we neared the end of our manufacturers warranty, I pulled the extended warranty out to make sure I was familiar with it and how it would cover issues...…………...short answer, didn't cover the issues I was concerned about. Called the salesperson, standard song and dance, refunded money on warranty.
That is my experience.
