Thanks to Boat to 5ver for stating something I have also researched. I worried about my 04 F250 CC SB 4WD being able to handle my 3055RL. It does have the factory installed overload helper spring set and upgraded tires.. I have seen this option called several things; hd pkg, camper pkg etc. I have weighed it at the same CAT scales 3 times now. Fully loaded, full fuel, construction type generator, small air compressor and 30 gallons of water and ready to go with Deb, me and the dachsund, I weigh 20300 pounds. The trailer itself weighs in at 11,750 pounds. Technically I am over GCVRW by 300 pounds. I am under the max on all axles. I spent many hours reading weight posts etc. on many web sites. The actual difference between a F250 and F350 equipped like mine is negligible. The drive train, suspension and brakes are identical part numbers shared with the F350. What is not shared is the door sticker rating, the tire load range and the F350 emblems. Although the weight concious people will dis-agree and they would be technically correct, I have no issues pulling my 3055RL. In fact, the truck pulls it with gusto. That said, I would want a dually one ton to pull any 5ver that has a gvrw of over 15000 pounds. The one ton SRW would probably scale ok but I would want the stability of the DRW. I understand that this opinion is worth exactly what was paid for it.
