I wouldn't take mine back to the purchase dealer to have them check the air in my tires. The Texas dealers, "Explore USA", seem to have tons to sell, but not even a tin shed for a repair department. A 10 amp fuse shut my jack system down. Couldn't move, period. They told me I should have purchased the extended warranty and I would have had towing. I asked how it could be towed with the jacks down. This turned into a rather heated argumet and was barred from returning to any of the Texas Explore USA dealerships. Does't effect me any since I wasn't planning to anyway.
