New 29' travel trailer dog walking

Did you hit any curbs real hard with it before you figured out how big it is? If not you, there is a good possibility that someone got the undercarriage hung up on something and brute forced it out. If it has leaf springs, it is possible to shear the locating pin or bolt off and shift the axle down the spring pack a little, bend the shackle mounts, or even bend an axle enough to make it track funny. A trailer tracking this much out of align is probably not safe to tow, at a minimum from taking up at least nine feet of lane or having an axle or two randomly fall off. I would call the dealer that you bought it and explain what is going on and get them to send out someone who has at least a little sense to do an inspection before anyone moves it (hopefully an insured hauler and not you). It should go back to the shop and be fixed (and documented as to what they did) right on their dime. Don't let them blow smoke up your tail by saying that they all do that, a RV hauler would not have accepted it from the factory that way and it will not pass a safety inspection that way (they did put a sticker on it that way?). If they just slapped an inspectin sticker on a dangerous vehicle without actually inspecting it they could be in trouble with the Tx DMV.
