Anyone know where I can get an accurate payload rating on my 2003 GMC 2500HD extended cab with the 8.1 engine? The various Edmunds, Autobytel etc. sites are all over the map. I could not find it on GMC's site, only the owner's manual which does not list the matrix. I am looking at potentially putting an Arctic Fox 811 camper on it (Dry Weight: 2873).
