I have a 1995 Chevy Silverado 2500 (not the HD!) and am thoroughly confused as to the tow rating. I didn't glean any info from the truck manual. I called 2 local Chevy dealers; one told me the rating is 8000lbs, the other told me it is 12000lbs. The truck has the extended cab, 8ft bed, 5.7 liter (350ci), automatic trans...I have no idea what the rearend ratio is. It also has a stock transmission cooler and what appears to me to be a factory-installed hitch, 8 lug rims with E load tires, so I'm supposing it has the "towing package"???... I want to purchase a fifth wheel and I need to know about the weight limitations...exactly how heavy a 5th wheel can I safely pull? And what length 5er am I limited to?
