I've made some progress on my trailer frame design but I am to the part where I need to design in the drop floor. I prefer the drop floors that come out all the way to the side of the trailer (like Doug's trailer) so you don't have to step down into them. My question is how do you determine how much you can safely drop the floor? I am guessing that wheel size and axle probably play a role in determining this but what is the minimum clearance etc that I should have?
thanks,
Lori
