Make sure you check your hitches. Today on the way to mow, my trailer started scraping when I stopped at a light. I got out to check and found the hitch had broken through the frame at the rear mounting bolts, and was hanging down from the front 2. The bad news is that it tore through the frame where the hole was, so I have some welding to do. The good news is that since the front bolts stayed, the trailer didn't come completely loose from the truck, which could really have been bad. I have a '97 GMC, with a Class III 2" receiver. It's supposed to be rated for 7500 lbs. I have a 6'6" x 12' trailer with a 36 wb, a 48" rider, 2 trimmers, and a BP blower and sprayer, all in Trimmer Trap racks. I haven't figured up the weight, but I can't imagine it being over 3,000 lbs. I have used this truck to haul my sister's Geo, and my Suzuki, as well as 6 yards of mulch, none of which should have exceeded the towing capability of the truck, trailer, or hitch. I just finished putting on a Class III step bumper hitch. Anybody here have any experience with one of these?
