Another item that may get you a lower priced trailer is if you don't need the extra width between the wheels / fenders. For example a 77" x 20' may cost a couple grand less than an 83" x 20". I found that to be true in my area. I opted for the wider with since I wanted to use the trailer for multipurposes such as hauling a full size truck or large car. They just wont fit on a trailer that only has 77" between the fenders. Most fullsize pickups are 79" or wider.
