I am looking for advise. I have a 2011 northtrail travel trailer. In september last year on my first trip with this unit one of the wheel bearings went out in Roswell, NM. I contacted my dealer. They sent me over to a local dealership. A new wheel bearing was installed, I had to pay for this out of pocket as the dealer had no interest in dealing with lippert for warranty. Sat night while traveling down I10 the bearing went out again. well less then the recomended service time or milage. But this time the wheel hub and all came off in heavy traffic on I10. I contacted my dealer again as I am still under my heartland 1 year. Lippert was contacted, They refused to warrant this item becouse the wheel bearing had already gone out once. I have contacted lippert's VP of warranty and as exspected I have yet to receive a return call. So hear i sit with a 3 wheeled RV stuck 1000 miles from home and heartland nore lippert will do any thing about it. How does that work when its a 2011 RV!!!!!!!!!!!!!. Is this a common problam when dealing with hearland and lippert?
