I wonder if anyone can help me out here. I want to buy a used '02 GMC 3500 4x4 crew cab with the Duramax/Allison combo. I need one for a large truck camper but I also needed it on the job once in a while. I have a Caterpillar Telehandler or all-terrain forklift that weighs approximately 12 ton. I am planning on purchasing a gooseneck 12 ton trailer to haul it on but didn't know if the truck would haul it. My only other option is to buy a 4500 with a regular dually bed on it but can't really afford it. I appreciate any info from you guys.
