Yeah, mine does that too. It makes about 10% less KW using propane vs gas. Nice option to have during a long outage.
Yes it is, I use both anyways gas in the Tractor, Propane in the grill and the flat top so it won't go to waste.
If the front weakens and lifts out sooner like the 18z Euro did going forward, And if Lee is slower on the GFS, Then there is room for Lee to come west.
