I'll be the third to agree that long beds need to be low.
When I bought my 05 Ranger. I was driving ~120 miles a day. I put 42000 Miles on that truck the first year. Only time it ever went to Ford though was for a bulletin they had about sticking throttle bodies. The warranty was up after only ~8 months. I then sold it to my younger brother to be a dependable college daily driver for him. I think he's up to about 65,000 miles on it now.
