My truck just barely fits on my trailer... its identical to the thrailer in 97crewcab's post. The fenders do rub the sidewalls though, so I have to make sure they are completely aired up. Though, I find it easier to just borrow my cousin's trailer, its 7' longer and about 2' wider, lol.
Make the fenders pivot on a bolt. Let one of them flip out while you load it, then flip it back up.
