I guess we'll find out today...we are planning on using heavy hardware so it's easy to get the bumpers on and off quickly (bolt and nut, but they are big!), although only two bolts per bumper.

Also we are not planning on using the aluminum angle, because it's so much work to make all those parts and screw them on. Lots of staples will have to do....again...

Thanks for the reminder to check weight before we actually put them together!
