Tried to update original thread on this, but it was too old.
Here is the final - I hope - Update. Finally installed the unit. It was somewhat of a challenge, but we gotter done. Had no choice but to vent out the front of our rig.
I was concerned about the machine because when I removed the travel lugs, the lag bolts were bent - indicating to me that the unit had probably been dropped. Ran a test load through it and it seemed to work just fine.
The DW is happy, so I'm happy.
August 2 we close on our house and give the keys to the new owners. At that point we will be full-time RV-ers. It's been a while coming, but finally here.
