I just finished putting some storage in the cabinet under my sink (aka, my 'utility room') Bought a rather beat up wooden wagon at a garage sale and toook off the wheels and handle. Painted it red (just because...
) and mounted some L brackets on the bottom. Drilled a few holes and mounted it with some bolts and zip-ties to the wall. Perfect fit!!
I also got a black wire locker shelf and it fits perfectly in front of the wheel well. It holds my rags, extra towels and washcloths. There's a couple baskets underneath that keep my dishsoap. bug spray, and extention cords.
Happy Camper with the results!
