I am going to sell my '89 F350 crewcab dually 2wd and buy a Chevy/GMC crewcab instead (or trade this truck towards one). It is a great running truck but I have had trouble with the E4OD transmission and heavy hauling. It can be built and upgraded but I would rather get a Chevy or GMC at this point. 1 Ton 2wd that gets 18 mpg empty and about 14 mpg loaded 7.3L IDI Diesel E4OD transmission with fresh rebuild, new HD torque converter, and some upgrades but overdrive went out on me HD Dana 70 Rear axle, 4.10 gears Good 235/85R16 tires Excellent body and interior (white with blue interior) Folding Gooseneck hitch RV 5th wheel slide in hitch 7 way RV plug in Bed Sliding bumper for hauling big camper (allows you to extend bumper to back of camper) 10,000 GVW Extra Core E4OD transmission Minor dent in pass side front fender and few scratches and minor dents inside the bed (it is a truck after all). $3000 as is with the bad transmission or add $750 and I will rebuild the extra core and put it in. Or trade towards a Chevy/GMC crewcab in good condition.
