We have 12 trucks. (2) isuzu tankers, (2) 1990 f250's, (4) 2001 f350's, (1) 2005 f550 w/ 6.0, (1) 2008 f350, (1) 1998 chevy 2500 silverado, (1) ford f150.
Overall the fords have been ROCK SOLID. No major problems in all of our 5.4's, all with over 80k. No problems with the 6.0 either but we've only put 5k on it from the original 40k we bought it with. Our only chevy we bought this year as a back up plow truck. Body has 250k, 350 gasser has 50k and tranny with 70k. Since buying it, everything is mechanically sound, only small things needing to be done. very comfy interior, I've actually been driving it around cause i like the interior more. The older fords have also been great trucks, both with over 200k, working daily in the summer.
We love ford and will stay with them. Next truck will most likely be a diesel 350 of some sort.
New dodges look real nice, New chevys i hate the looks. Couldnt give an opinion on reliability or interior BUT id say about 70% of the work trucks i see around here are fords.
