I think we had a bent axle when our 2013 22FBS Northtrail Caliber Edition was new, but the salesman convinced us the wheels tilting strangely was a "feature". Two axles later and three tires later, we upgraded the whole undercarriage last Spring. For the first time ever, we took a long trip without a breakdown. We upgraded the stock C rated tires to Maxxus 8000 ST8000 . We went up a size on them too. I think they are 15" instead of 14" Rated E. 5200 lb axle upgrade as well. The rig sits an inch higher but not uncomfortable or unsafe. Along with that we redid all the suspension, brakes, and of course wheels. Got the EZ Lube to keep the bearings greased easily. My question is this: Anyone else have this trailer and axle problems?
