Estimating an 8 foot width side to side, you can use the formula "100 X rise/run" to convert inches to percent. A one inch rise (a one inch pad under the wheels), would equal 1% of rise.

100 X (1" / 96") = 100 X 0.01041 = 1.041%

At least that's what I learned on the internet.

How do you convert .25 inch per foot into degrees or percent slope

And I know, degrees isn't percent, but I thought the formula was pretty slick.

Here are more formulae for slope calculations, for gradient, percentage and degrees.

Finally! My math teacher was correct. After 50 years, I do need to use my Jr. High math!

Large level on the front of my 5W each mark is 1" so if I'm two off center raise 2" or drive up on the Andersons and watch for center.

Just make sure if it isn't level that the slope is to the wife's side of the bed.

Dusted off my trig skills and figured out the numbers for my trailer. Front to back was a little trickier and I measure from the front levelers to the pivot point on the axles.

L to R: 1º = 1.67"
F to B: 1º = 3.35"

Since I have the auto-leveling system I just need to get it close so none of the legs get out of stroke errors. To keep it simple I'll use 1.5" per degree L to R and 3" per degree F to B for calculations.
