Truxedo deuce for me. The TruXedo Deuce features a quick-release latching system on the 30-inch wide front panel making bed entry convenient from both driver and passenger sides of truck. It is easy to install and remove. It comes pre-assembled with quick attach cover system and no-drill clamps. I have a 50 gallon aux. fuel tank in front of the 5th wheel. It fits under the cover and with it opening at the front, I can fuel up without having to roll the cover up. I can also roll the cover over the 5th wheel when not towing.
Another vote for the Truxedo deuce. I have a tri-fold on my 2013 and I don't like it because when folded up to expose the full bed, it completely covers the rear window. When I saw the Deuce, it was my choice for the 2015 3500 tug.
