@Artie I got 4 of the 1up racks. I also carry around a step stool to get bikes up there. It's a pain at first, but then you start to figure out tricks the more you use it. Smaller bikes in the middle and as far forward as you can. Then the larger ones on the outside and as far back as you can. When unloading, do the back tire side first, then move the whole bike backward so you have a non-pivoting tire holding the bike up while you open up the front.
