I got this for the garage of our Grit Overland GO/AT adventure van. I mounted it to the 2 L-tracks that we have in the rear. I was told this would not support the full 500 lb rated capacity, but that isn’t a problem. It will be primarily used for bikes.
I had to drill holes because existing ones didn’t line up with our L-tracks. It is aluminum, so that was easy to do. I used L-track studs to connect them. I had to use shorter nuts than the lock nuts that came with them to keep them from scraping the bottom of the tray. I installed them with locktite in hopes that it will keep them in place.
I installed 1 piece of L-track in the front and one in the rear to use with Freedom Coast L-track Fork-mount bike mounts. They are pricey, but the adjustability was important. The L-track holes on the front and rear of the tray do not fit the double-width L-track mounts on these tracks. Also, they are too far forward in the trays for drop bar bikes because the bars extended beyond the trades. I am able to get 2 drop bar bikes to fit within the 20” wide tray by putting one facing front and the other facing the rear. The wheels fit on the outside of each bike in the space created by the handlebars. Our bikes just barely fit under the bed in our van.
The only negative is that the screws holding the trays to the sliders vibrated lose the first time we used it: there are no lock washers and they were not installed with locktite. I reinstalled them (a little tricky since the rear is not accessible for several of the screws).
Overall, I love the arrangement. It slides very easily and fits perfectly in our space. It is a lot easier to get bikes in and out with this tray than trying to position them inside the van directly on the bike mounts attached to the L-track. When we aren’t using them for bikes I think it will be very convenient for hauling other stuff.
