My last trailer was a 14,000 # 30 ft deckover with stand up ramps. It had a beavertail so the ramps could be laid over all the way to make 30 ft of flat deck. Depending on the load distribution I could move equipment foward, drop ramps all the way over and then drive to wherever the load rode best. when I got rid of the F-20 didn't need the deckover. My new trailer is a 14,000# but with a lower deck with 83 inches between the fenders. It has the slide out ramps. You have to be careful with the slide outs because if you aren't lined up perfect the ramps can flip. Don't ask how I know. Looking for a way to secure ramps to keep from flipping when loading as I am typing this. Other than the ramps slipping I like handling the slide outs better. At 70 with a bad back, Bad legs ,etc the standups were getting pretty heavy.
