Sorry, I have a 2014 Ford FX4 and a 2011 Aspen Trail 2810BH. I just returned from a level parking lot and trying a bunch of things.
The trail now sits very level when hooked up. There's myabe 1/2" in difference from front to back.
The truck drops just 2" in the rear.
However, the truck is perfectly level measuring both the front and rear wells.
*Ford trucks seem to sit higher in the rear.
This is how it looks now....just the torsion bars are a little high, I can't get them level without keeping the trailer level.
THe torsion bar system is a Curt 17001 System.
