Answer: Whew, that's a tough question! I am afraid you'll either have to custom make the caddy, or have it custom made. Making it yourself wouldn't be too difficult. You'll need wood cut to shade and some heavy duty casters that you attach with screws. You can get the parts for your project from Home Depot and they will probably cut the wood (particle board painted with waterproofing stain would be good).
Best wishes with your project!
