ideas for engel fridge box

Hi,

I have a SR5 hilux and I am after ideas for a storage box in the back for my 40l engel.

I don't have or want a canopy on the back but I do have a draw system that raises the floor to the top of the wheel guard's. I also have alloy ladder racks and roof basket that would prevent some ideas I have seen where the box lid open's from the top. I was thinking it would be better to put the opening at the tailgate end of the ute with a fridge slide that pulls out and down. I welcome advice on the best brands or options.

I guess to some it up, I want to come up with a fairly common (draw and fridge) canopy set up. Except I don't want the canopy. I do however want to keep the fridge out of the weather dust and water.

Thanks
