1990 ford F250 4x4 Plow truck with Western Plow

1990 Ford F250 Plow truck, rusty but runs strong, used the last 5 years to move snow on our acreage, we now have a surplus of other equipment to move snow and no longer need this truck.
Last spring the fuel pump relay burned out- it will need a new relay to ruin, tires are 70%, new fuel tank and fuel pump, ignition switch is worn so we have added push button starter switch, you will need to bring a trailer to transport truck unless you live within 100 miles or so...truck is guaranteed to run once relay is replaced but it never liked running long runs on the highway with the plow in front- it had trouble staying cool due to low rear end gearing, although it never had this problem while working moving snow, only at prolonged high revs on highway
