Bathroom Storage shelf

[engnrsrule]

My 2006 Roadtrek has a bathroom shelf molded into the sidewall. Items are held in by 2 flexible plastic rods. One broke on a recent trip and I wanted something less flimsy.

I found driveway relectors at Home Depot that are on a fiberglass rod of same diameter but are significantly stiffer than the plastic rods.
