I have a 2014 Torque 325 SS VIN#5SFCG382XFE288554, I had a blowout coming home on my last trip and destroyed the fender skirt on the driver's side where the slideout splits the fender. Where can I purchase a replacement for this, my RV Repair shop is having trouble locating one. Also, since this is my second blowout this season, I am considering upgrading the tires, is there a G rated tire that would be compatible with this trailer.
