We own a 2013 Grey Wolf Select 28BH. Our only issue after a 4000 mile trip was excessive tire wear, especially on the left side. Problem was improper alignment. Also bent one skid plate due to inadequate clearance. Forest River installs the cheapest axles and tires. So I had the axles replaced with 5200 lb. axles (and cross bracing) and upgraded from 13 inch tires and rims to 16 inch tires and rims (Maxxis 10 ply E rated radials) and changed the skid plates with square tubing and 4" wheels with cross bracing. Also the springs were strengthened by adding extra leafs. This increased the clearance considerably. All travel trailer owners should have the axles and wheels aligned before any long trips to avoid excessive tire wear and blowouts. (Blowouts appear to be a fairly common problem on these forums). When replacing tires, definitely go for the Maxxis radials.
A strong undercarriage will prolong the life of a TT.
