Absolutely fantastic

In a world where a lot of companies make large promises and then do not deliver that is not the case with diabolical. I called them with an inquiry. They told me when everything will be shipped and it was shipped by that night. The packaging was absolutely fantastic even though one of the boxes look like a forklift Tying had hit the box. There was no damage to the product inside whatsoever. I purchased the full system for the back of the ineos Grenadier and a pump from a couple of nuances Ian the videos everything fitted perfectly. It’s very very simple even as a single person working on this it worked out beautifully and it carries absolutely everything that I need.

Grenadier Upper Deck

Awesome company! They replaced my Slipstream lock nearly 5 years after I purchased it, at NO CHARGE! Their products are secure and stout, and they stand by them. Highest possible recommendation- the only way to make your jeep cargo area secure.

Amazing quality and functionality

The only thing I would improve is some simple install instructions with torque ratings or a QR to a short video.

Awesome addition to a already awesome vehicle

The deck essentially increases the packing floor footprint by almost two thirds and by adding the 4 inch lift to its existing mounting brackets allows for about 16 1/2 inches of space between the floor of the drawer system and the mid deck. Enough space for a Coleman steel belt cooler and Yeti totes. The system is modular in that the mid deck is held in place by 4 Nylon star knob nuts allowing easy removal. The deck is rock solid once locked in place.

Screws

Having the ability to hand tighten and then quickly loosen for removal would be a nice upgrade given the shelf is great for camping but would be nice to easily remove for dump/store runs.
