On the 235S we had about 6 inches of clearance under the rear tire. I had two triangular drag bars welded to the rear of the chassis to protect it. Way early in this thread I remember someone talking about having lost a spare going down a driveway. That made my mind up.
I also hate the table mount. Mine has taken to shakin' and rattlin'. It looks like the bracket with the tongue on the table has bent open a bit so it doesn't pull the table tight enough. I'll try to fidget it with this weekend while we're camping.
