Looking at the 130WB, Med Roof Transit for a custom "ClassB" RV.
Relatively light build, no thick particle board cabinets or roof AC.
No towing planned. But liquids are heavy!

Just finished a chat session with Ford to answer some questions.
The differences between the 150 and 250 are 400lbs payload, $940 base cost. Towing capacity seems to be the same if all else is equal (engine, axle ratio). Vehicle weights are the same (with the same engines). 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.
If I don't need the extra 400 pounds payload, what's to choose between the two? 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.
What's to choose between the 3.73 and 4.10 axle ratios? 10% lower RPM, a little quieter, better MPG on the flat, but worse acceleration, esp on hills?
I notice the 3.5eco has a 3.31 option, which might improve MPG and noise level, but I'll almost certainly go with the 3.7 for cost and simplicity.
I'll be curious to see what the actual load height is. Specs show 28.2" for MWB, 28.8 for LWB. By contrast, the Dodge Ram Promaster claimed 21", but I measured 25.5 in the rear, 23.5 at the side, empty, quite a significant tilt.
