Hi, first time posting here. I'm looking at buying the above mentioned truck with about 160k miles on it. Seems to run great, but I am having a hard time figuring out what the payload capacity is on these. GVWR wasn't on the driver's door. I want to use it to carry a truck bed camper that will weight about 5k wet.

Its a regular cab with a 10ft service bed with tool boxes on either side. Curb weight is stated at 8,600. Does anyone know the GVWR for these trucks? I am also unsure if this was a regular pickup converted to a service bed, or sold as a cab and chassis. Wheelbase is 160" would that affect GVWR?

Any other thoughts or things to look out for with this truck?

Thanks!
