Today I installed my new hitch I received from Atlantic British and I also fabricated a floor for my expedition rack. Its made from 3mm aluminum and it only covers about half the rack. I didn't want to block all the light from coming in through the glass roof, but still wanted protection on top and be able to put jerry cans up there like the Discovery LR4 1,000,000 edition. Still need to put down some grip tape and get another eye lashing bolt.
