This truck was a maintenance nightmare. If I did not have the factory service manual and the TSB's it would still be dead on the road. If I did not do the maintenance myself I would be broke.
The truck was comfortable and quiet to ride in. The seats were comfortable, but the passenger seat foam had been worn out by the time I sold it.
It averaged almost 20 mpg overall with a high of 26 mpg on a 60 mph trip at 1000 ft altitude.
It had plenty of power. Off road it was very good. It did the Poison Spider trail in Moab Utah with a few sneaks.
It seems pretty rust proof. Some rust on lower tailgate. Montana does not use salt though.
This truck was nothing like my Mazda RX-7. The RX was the most reliable car I have ever owned.
So much for a re-badged Ford Ranger.
The B4000 is gets a safe vehicle discount from State Farm insurance.
Overall, I would not touch another Ford product in the foreseeable future.
It was replaced by a Nissan Pathfinder.
