I'm picking up a grandma bear with arched doors and bolted on legs. it seems like it has a bottom heat shield but I couldn't see how it was attached. I was hoping to put this on a dolly with four caster wheels to move it out to the trailer, to bring it home but I'm worried about damaging that bottom heat shield. Anyone know if either I can remove that bottom shield, or otherwise how to transport this thing? thanks in advance.
