Recently had a chat session with Ford to answer some questions about 150 vs 250.
The differences between the 150 and 250 are 400lbs payload, $940 base cost. They couldn't give me any more information re: springs, shocks, etc. They thought towing capacity would be greater, but all published specs say towing capacity and all other specs are the same if all else is equal (engine, axle ratio). Vehicle weights are also shown the same (with the same engines). For 130 WB, Med high top, 5060 with 3.7, 5130 with 3.5eco, 5500 with 3.2 Diesel, so engine choice, especially the diesel, eats into payload.
Chat person said ground clearance is 6 inches for 150, same for 250. She didn't know if this was empty or with rated load.
Seems like the 150 might ride a little better, less harsh, but it might also be more susceptible to wind. $940 buys some nice options.
Planning 130WB, Med Top RV
