There's a 15k Carrier Air V on the 5th wheel it's a no go, shuts the Magnum down. I need to add a soft start, luckily I can move with the weather while boondocking. I've tired it with the eu2000i and it's hit and miss for shutting the Magnum down on start up. Maybe the eu2200i I just got will be able to handle the startup?
I tapped into the furnace heat duct where it ends above where the batteries are in the front compartment. I can pull the cap off the end of the tube when below freezing temps. This was keeping batteries in the upper 30s to low 40s while it was single digits outside during the night and below freezing during the day.
