I think the ramps are about 20 odd degrees.

The maths is

r=d/b×1000
d=distance travelled up the ramp
b=wheel base

At tuff trucks they add wheel track to the formula, but I dont know how or where

yeh cheers. done a bit of research and will be starting the ramp soon.

Are you going to do a bit of Trig (Cosine Rule) using 20 Deg as angle?
Be mindful of your liability using the ramp and that it is deemed to be safe & suitable for its intended use. To cover yourself get a certified ramp or get your design and build certified. I am not an engineer.
