Don't have a clue. What ever is factory instl from THOR on the 2018 ACE.
The gen is; Onan RV QG 4000 Gas Generator
I would love to have the auto start when the shore power is loss.
Why would the unit no longer be available since 2015 and they still install the QG 4000 unit in 2017 / 18? Just curious.
Ours is a 2018 THOR ACE 29.3
