H-F sells a bead breaker for $40 but I don't know what your storage limitations are. In the past, when I've had trouble with a tire, I just got frustrated and drove over the outside edge of it with the truck...
This is of course, provided the vehicle is still mobile and you're not worried about damaging the tire.
For mounting/bead seating, I've found that a ratchet strap around the perimeter of the tire works well.
