Anything over 14 doubles the fuel mileage that I get with my Ford V 10, when “NOT” towing anything! memtb
That's why I avoided the V10, lot's of those on the used market awaiting their next victim.
My Chevy 6.0l vortex gets 10.4mpg @ 65mph pushing my 28ft coach down the road.
70mph knocks me down to 9.6mpg.
The fuel economy those coaches build on the Sprinter chassis get is about all I find desirable about them for my needs.
Now if a guy were to pop for the $200k + model and get the lifted 4x4 version it might be worth dealing with the more compact interiors.
