Buy the truck, that is a hell of a good price, if he worked at it he can easily get 15-20,000 for that rig. They sell for 8-15 U.S. very regularly, and with more miles. The V10 will easily run 600,000 Klms.
I carried an 8.5" heavy old style Vanguard camper in mine for a number of years. You can still see the camper tie downs in the pictures. That 3/4 ton V10 has lots of power and the payload to carry it. This is mine, 260,000 Klms, runs like new, does not burn a lick of oil between oil changes. As far as gas mileage, whatever you put the camper on is going to get ballpark 10 mpg. That is about what the V10 will do loaded too. Mine does about 14 empty on the highway and did 9 with the camper, pulling 4,500 pounds of tournament boat. My new 2500 only does about 17 or 18 empty so I am never going to save the purchase price on the "improved" gas mileage.
Just bought a new 2021 2500 but am holding onto this truck till I am positive I like the new one at least as much.
