Cornerstone warranty their service is useless !! Nationwide
I purchased an extended warranty through cornerstone for for travel trailer i purchased new a year and a half ago. Recently i was camping in the Smokey mountains and my power inveter fried, it was Sunday, father's day, i had to contact a mobile technician to replace it (400.00), cornerstone denied my claim because i didn't contact them first, so don't waste your money with these people! Their service is non-existent and useless!!
