I have a 1983 Fleetwood Southwind on a GM frame. Three years ago the transmission began cracking around the bellhousing. I replaced the transmission. One year later that transmission cracked in the same place. So I put in another one, along with new motor mounts, U- joints, and hanger bearing. I drove less than 500 miles when the transmission shatered, it turned sideways. Now I'm 480 miles from home and had to find a RV repair shop. It cost $4100.00 to get it fixed. Then I drove home to Tampa from Pensacola 480 miles and found the transmission has began cracking agin. The drive is all flat road and I was not towing anything. I bought the motorhome with 56,000 origenal miles. It has not been in a wreck. What else can I look for.

Are there any driveline vibrations or U-joint concerns? How about dowel pins... are they installed and in good shape?

This sounds like a vibration or alignment induced failure.
