On my previous truck we used the Extang TuffTonno Peel & Seal Roll Up Tonneau Cover it was a 2012 Ram Mega cab. Worked excellent for the 3 years we had the truck. Truck was only used for towing our 5th wheel.
Very easy to take on the off, rolled up nice against the cab and the material never marked up the cab.
We purchased the same item again for our new 2016 RAM.
They have up graded it here and there. They added a bar along the tailgate to make removing the cover easier and it rolls right up with cover to the front. The new tension bars that go across the bed are ok. They have a new spring loaded assist, they are ok seem to work good but we liked the solid aluminum ones like before.
Ordered both from autoanything.com after searching other sites and talking to local auto shops. They had the best price.
This is the 2012 Mega. Don't have a picture of the new one yet.
