Testing how far up a steep ramp is a good measure of the articulation and suspension travel you have in a truck.
Einar was watching over the test and did some demonstrations on how much his Cherokee is able to flex.
This Grand Cherokee on 38 inch tires is able to flex almost as much.
My unmodified Sport Trac is rather weak in this area. As you can see it is scraping the ramp.
It is good to have a "before" picture. After the planned modifications this will change a LOT! I am going to put a Dana 44 front and a four link air-spring suspension rear
