Hi, I have a 1/2 Ton GMC Suburban with a 6.2L Diesel two wheel drive. I have done some research online to find the towing capacity of this truck and I have yet to find the same answer twice. I have found everything from 5000lb to 9000lbs. I am looking to purchase a travel trailer to pull behind it and I don't want to overload the truck. The owners manual is very vague. The GVWR on the truck 7100lbs. The numbers stamped in the reciever hitch are 4000lb trailer w/ 400 lb tongue dead weight and 10000lb trailer w/ 1000 lb tongue with weight distributing hitch. I know thats what the hitch is rated for but that doesn't tell me what the truck is capable of pulling. Any help here would be great.
