vtraudt, I have another idea for you to consider. I purchased a Level Mate Pro system for my trailer. It is an electronic gizmo that I use with my cell phone. When I get to the campsite, I turn it on and it tells me that I am off by 1.5 inches on the driver side. I have a combination of planks and boards that I can drive up on. Bingo! I am set. I don't have to guess and make a number of tries, just put in what I need and I am good. It is a bit spendy but easy to set up and really easy to use. Used it for over a year now and it continues to simplify things for me. Google it and learn more.
