I have a 2009 GMC 2500hd diesel. The door sticker indicates a GAWR RR at 6064lbs and GAWR frt at 4860lbs. I am interested in buying an artic fox 811 truck camper with a dry weight of approximately 28...
No, your truck will not handle it. I had the same truck as you and the payload sticker was in the glove box door. Payload was less than 2000 lbs. 4000 lbs is 3500 dually territory. Get the proper truck and keep the rest of us out on the roads safe.
BTW my dually's payload is just shy of 5,000 lbs and my trailer puts 3500 lbs in the bed.
