This is a copy of a Post Reply which I had previously posted in response to another operator inquiry, our previous TV had a short box:
Our previous TV had a flip cover, we loved it except for one thing. The cover sat on top of the side rails, cutting into the TV/5'er clearance. Once folded it added about another 1 1/2 inch to the side rail heights... which we could live with, but, the latch on either side added another 1/2 inch of height. On one occasion I did gouge the 5er on the latch. Not a happy day!
On this TV (long box) we installed a Roll-N-Lock along with the matching Cargo Manager. It's mounting rails sit flush to the TV bed rail. And when rolled up it adds no height to the truck rails. You do lose about 8"x8" square box at the head of the box to accommodate the fully rolled tonneau. The Cargo Manager adjust along the side rails. Once we install the 5th wheel we set the Cargo Manager just in front of the 5th wheel, we set the adjustable tonneau cover to match the Cargo Manager and have in effect set up a semi secure storage area at the front of the box.
PROS: It clears the hitch and Cargo Manager. When closed it does lock the tailgate. In our case we have both a locking tonneau and OEM locking tailgate so storage in the bed is fairly secure.
CONS: The locking mechanism does freeze up, snow build up does hamper your ability to close the cover. Requires a little work to get access in certain winter conditions.
To each his own, but all in all the Roll-N-Lock and Cargo Manager meets our needs and expectation.
Happy trails ....
