Ok I went and test drove an 02 1500HD with 6.0 and an 02 1500 with the 5.3L. I was not impressed with the get up and go of the 6.0, and I forgot how terrible the turning radius is on the GM HD trucks. I was impressed with the power of the 5.3L, they seem to get up and go much better then similar year F150s with 5.4L. Now I have to drive a 8.1L truck to see if its worth me getting a 2500 series truck.
Sounds like 1500s and 2500s have simiar issues
Front wheel bearing issues on both
transfer case issues on both
junk bodies on both (rust)
