I have a 2021 Ford Super Duty (F350) which are taller than most pickups. I had my truck lifted just 2" and it's on 37" tires.
My 2021 Montana 3120RL measures, on a flat street, 14'0" to the highest point which is the front A/C unit.
This pic was taken in a driveway and the street is lower - you can see the trailer is a bit nose high.
