I would contact Wholesale Warranties in San Diego as they are a brockerage and will find the best warranty for you. I have used them on three of my tow vehicles and now on my motorhome. I have only coach coverage and not wrap as I didn't think that I would need wrap with my rig. WRONG
I do have the coach coverage with Cornerstone and it has worked out for me, especially when the fridge cooling system went out and the jacks quit working. It has paid for itself several times over.
