Since someone just put out a review of the Top Dawg, I thought I would post a few comments about my new tonneau and why I like it.
I looked at a lot of covers, including rigid designs like the Top Dawg. I needed access to the whole bed for loading motorcycles. While some rigid designs are removable (with varying degrees of effort), you are left with the problem of stowing the cover somewhere while driving the truck.
I can't imagine how I would stow the Top Dawg cover in the bed alongside a strapped down motorcycle in a way that would not catch wind, and would not get that thin aluminum dinged by foot pegs, exhaust, dirt bike skid plate, or some other part of the motorcycles I carry.
A roll-up seemed like the perfect solution. When I bought the truck, I had the dealer install a tonneau as part of the deal. It was a Black Max snap up design. This was my first pickup so I had no prior experience and the cover seemed OK - that is until the first time I tried to resnap it on a cold day.
For two years, that cover lived on the back of my truck all rolled up because it was too much work to resnap it. I needed something different.
I looked at a design that was rigid, made from slats, that rolled into a box at the front. But the box was too big and didn't allow the front wheel of the motorcycle to rest on the front of the pickup bed. The tonneau enclosure pushed the bike back about a foot. Not ideal.
Then I discovered the Access roll-up cover from Agri-Cover. Pics and a video are available on the mfg website. Mine looks exactly like the one pictured, both deployed and in the roll up position.
This is a soft tonneau with integral rods that roll up with the cover. The sides are closed by hook and loop (Velcro).
On the Taco, the side rails are mounted by first removing the sliding rails, and bolting the cover side rails underneath the sliding rails. Action of the sliding D-rings is maintained.
The angled sides provide mechanical advantage, giving the Velcro extra bite. A lever action at the rear of the cover by the tailgate pulls the cover closed tight with little needed effort, providing a perfectly flat cover that moves very little when driving.
What I like:
No more having to remove and stow supporting rods as with the snap-on cover.
The integral rods mean the rolled up cover maintains a horizontal form when rolled up instead of sagging in the middle. It also rolls up into a fairly compact package. Nice.
It rolls up and deploys back over the bed quickly. Running your hand down one side then the other seals the Velcro tight.
They offer a tailgate seal but the Taco seals well without it. I put luggage in the back for a 1200 mile winter trip and everything stayed clean and dry.
The cover doesn't have a keyed lock. A locking tailgate would be required for ultimate security. However, I like the ability to open the tailgate without lifting the cover.
The cover has tension adjusters to tighten or loosen the cover based on season and possible future stretch. They operate by moving the front of the cover (by the cab) fore and aft with screw type wheels.
I can unroll, load a bike (using the new D-rings I installed in the front floor), drive, unload, and cover up easily. Very slick. I have had the cover since early December (almost two months of winter usage) and am extremely happy with it. I have performed the roll-up and deploy procedure about five times so far and the cover rolls out tight and remains calm on the highway.
