We've been talking about switching to a pin like that... I really hope we finally do it this year.

Can you expand on the light green bumper mounts? Is it a piece of C channel with an additional L bracket on top? Was this primarily for additional support vertically, as the bumpers are really only supported along the bottom edge by the frame?

We always try to keep our frame in the center of the bumpers, which has allowed us to use some C-channel sized to fit snugly over the kit frame, without any additional supports. Of course, we've always used nuts and bolts, so it's been a pain to take the bumpers on and off. Fortunately, we've used reversible bumpers the past two years, so that hasn't been a problem!

Bonus points: attach the pins to the bumpers through a small cord (many of those quick release pins have holes pre-drilled specifically for this!) so you don't lose a pin!
