I carry a portable folding ladder with me (a little giant style ladder). I use the ladder for loading and unloading the bikes. I bought it knowing that I needed some way to clean the sticks and pine cones off the top of my slides before retracting them. It is very handy for both purposes, but a bit bulky to carry.
I am able to load the bikes by myself. It is helpful to have someone standing nearby to hand the bike down to, but about 90% of the time I end up performing it solo.
