Wholesale warranties has an excellent reputation as an RV company. They have been a fixture at many RV rallies and shows. When I had a warranty problem, and they were the agent, they went out of their way to make sure everything was completed to my satisfaction. Helped make the claim, followed up, called me regularly to make sure the work was progressing. I could not have been a happier camper (well maybe if it didn't break in the first place). I won't try to compare the to companies, since I have no experience with GS warranty.
