So I drive a 21 year old F150 that I love. Only problem is that the previous owner beat it pretty bad and now things are going wrong and I can't keep up on my beginning farmers pay. Haha. So the question ultimately is, because I want to move to a diesel and I will only buy a Ford, would it be worth my time to buy a used service body F350/F450 with a 7.3 Powerstroke for $3000 and sell the box and replace it with a regular box or nice flatbed? There are one each of the listed trucks they're around the 2000 model year.
