Example: You need to set the truck height to 14' 10"
In height settings you input 14 and press "done" then "back" and tap on the white part of the screen and it should show 14'
tap 10 then "done" then "back" and you should see 14' 10"
Do this for any other feet and inches needed, but always go "back" to check you got it right.
