Good evening. I have been diligently searching to get confirmation on the weight of a travel trailer I can tow with my truck. My truck is a 2009 with 40k miles on it. I think it has the K5L "Equipment Enhanced Cooling Package" option on it along with the KNP "Cooling System, Transmission, Heavy Duty, plus the VR4 "Trailer Hitch (Weight Distributing Platform)" and the Z82 Trailering Package (Special) (Reese Type Hitch), but I am not 100% for certain. I do see in some paperwork that the GVWR is 6001-7,000 range and the GVW Rating is 6800 (did not see GCWR). I also did not see any trailering information stickers other than one in the glove box that said it should not have a slide in camper. I am considering purchasing a travel trailer, and the dry weights of the units I am looking at are 6,550, 6819 and 7,020 respectively. I do not want to tow anything that will be an issue. Can anyone give me good information on what weight I can tow?
