I purchased a 2012 Shadow Cruiser 280 QBS. It was used. After 3 trips we noticed the insides of the tires are worn. After reading these forums I have called both Cruiser RV and Lippert. Both are well aware of the problem. Cruiser RV said they would not do anything for me since I am the 2nd owner. Lippert said they could possibly supply the axles free of charge but would not pay for labor. I have it at the dealer now and we are trying to get the extended warranty to cover it. The dealer is saying we should try aligning and calibrating first before getting new axles. Has any one else tried that?
