2005 GMC SIERRA 2500 HD DIESEL 2WD W/SUPERHITCH & SET UP FOR TRUCK CAMPER

2005 GMC Sierra with relatively low miles. Engine and transmission are both excellent and have never had any problems - not sure what particular model diesel engine except that it is the good one that they changed to in 2005. Has a super hitch and is all set up for a slide in truck camper. Crew cab and 2wd - body is in good shape but has various dings and scratches typical with a truck this age. I recently switched jobs and don't have a company vehicle, o I need something that I can pound miles on at 35 mpg.
This truck consistently got 20mpg ish on highway and averaged out over 10,000 miles at about 18.3mpg. Added pic of only rust I can see on the truck which is the bottom of the tailgate. Since a few people from far away are looking at the truck, am about a 45 second walk from a major train station. Originally posted mileage on truck as 174k, ut as you can see in pic it is just shy of 178k
