I've been using an old $25 mail cart from a junk shop for the last 20 years. I cut a piece of 1/4" plywood with 1x2 strips screwed beneath for rigidity and to keep it in place, plus a hinged door in the top for access to the top basket for towels, gloves, chicken roasters and such. I left the bottom basket open for wood chunks, spray bottles, spare grills, etc. Six inch wheels in rear and casters in the front where the push handle is. The Smokette is not bolted down, but has never slipped a bit & I don't push it far.
