My neighbor just bought a 40 ft trailer to get into an over the road hauler job. We were talking over the weekend about how to/ or if you could get adapters for the rear axle to make it a dually? I assured him that adapters were out there and am asking here where to get them and how much? Also, can the new 1 ton dually truck bed "fender flares" be grafted or just simply bolted to his '05 short bed wheel well openings to cover the extra wheels sticking out? Thanks for your time and help, Chris.
