I have a 1999 f350 2wd 4 door and it is the best truck i have ever bought. i get average of 18 mpg and i have an edge programmer and i pull all the time when i pull i get about 15 mpg i have 275,000 and i change the oil every 10,000 miles . it is very reliable and im looking to replace it when it hits 300,000 miles i just want to up grade to a newer truck and i want a 4wd truck. it only uses 2 qts every 10,000 miles cant ask for a better truck. ford is built tough .
