My current truck is a 2000 psd. The cross members for the bed have rusted completely through. If I were driving at elevation, a turbo would be mandatory. On the interstate, it pulls an 8500 lb travel trailer better than my '93 did, but the IDI did better at pulling a 10k load up out of the creek bottom. I'll need to replace the PSD soon. No idea what I'm going to do then. With the current options, I'm thinking of piecing together a Fummins of some kind. I've never owned a 5.9, but I've always believed it was the best truck motor on the road. When the industry tanked in '08 and Chrysler was in bankruptcy, Ford should have gone after a contract with Cummins. If nothing else, they should have tried to get a 4bt for the F150 so they would have it available for the new Ranger.
