Same issue. Foggy at start up in the morning. Easily fogged when slight rain or cooler outside temps. The huge front windshield does take some time to de-fog but generally stays de-fogged after the Ford defrost catches up. The side windows are our biggest issue. Constantly fogging up as we breathe and provide warmth to the cooler window. Defrost has really no effect on these windows as everything is piped for the massive front windshield.
We did a small fan in the lower corner which almost fully fixed the fogged up side windows. Seems like Thor could have ran a single smaller duct on each side to address this issue.
Rechargeable mini fan does just fine. No cords, no batteries, easy to move, decent performance on a charge.

Since I have two separate thermostats, I simply put the rear on on heat from the heat pump and the front one on A/C and warn dry air comes out of the vents. That will defog the entire coach in about 15 minutes.
In the previous coach with only one A/C, we ran two small electric heaters with the A/C to dry-out the coach in the morning. When driving a warm rain, we often ran the propane wall furnace along with the generator and A/C, as the coach had no dash A/C.
