My brother had a collection of old trucks and his R700 is the last one left. It was a factory ordered R700 with a 1693 cat 425 hp with a 13 speed on camelback , truck was ordered at York Mack in pa . Truck runs but needs some TLC , top of cab is rusted but the best part is it only has 320,000 original miles on it , it was bought just to pull a low bed trailer around for a small paving company. My brother was hurt really bad in a truck accident and my family has been selling off his collection . The mack is the last one to be sold . Like I said it needs a little work but it's a sweet old piece of trucking history ! I haven't seen another one with a factory cat engine in a R 700 ! We are asking for $6500.00 it will have to be towed home . Call or text me at 609-381-7795 truck is in monroeville ,nj 08343. SOLD ! Thanks for all the calls , we just sold it .
