hey guys! i just bough an 01 f250 ccsb 4x4 4r100 lariat 7.3 truck. this truck is a big upgrade in every aspect from 1990 RCLB f250 with the 7.3 idi except for the fact that it seems to drink fuel like no tmmrw.... i average 13 mpg in the city and 16.5 on the highway. my idi didnt care how it was...
