Farrier Rob McCumber used to pull a walk-in shoeing trailer with his pickup truck. But then the homeowners' association in his Boynton Beach, Fla., neighborhood banned resident parking and storage of commercial utility trucks, so McCumber had to find an alternative.

Let's say you're performing your daily shoeing work and you're at a location where it's tough to pull your rig close enough to where you're working. And let's say that you need to do some minor fitting adjustments to a shoe that you're just about to put on a hoof. Do you really want to set the hoof down, come out from under the horse, walk all the way to your rig, make the required shaping adjustments with a few hammer blows and then walk back to the horse and hope it fits?
