Bedlam,
Now that I think about this, a former now deceased moderator bought a Tiffin. Tires on front were not capable of front base weight. Tiffin put on higher ply tires with enough capacity, but still not wide enough to meet bridge law specs. He died not long after, so not sure how this was resolved. He was sold per our state laws an illegal rig! IE, initially 245 22.5 rubber on front of rig that weighted over 12,000 lbs. Ply rating ok, too narrow for the how much.the front weighed!
Something for many to think about.
