On my Ford F350 Crew Cab, Short Wheel Base, I have a 70 gallon TransFlow bed tank, so we couldn't have a slider installed.
Instead they put a 10" extension set-up on the trailer hitch, so now I have the clearance I need for a short bed without a slider hitch.
The only thing I have to do now is lower my hitch in the truck 3" as I have 10" clearance.
