Hi,
Running one fan @ 4 amps will take the battery down to 50% state of charge in 14 hours. If I add another 2 amps for parasitic loads, that number drops to around 8 hours.
Recharging with the truck will take many hours.
I would run the cords myself. You may wish to power only the converter. Mostly they may work well down to 102 volts. An Iota will still work at 95 volts.

The RV has two Surflo Comfort Air powered vents, and I was wondering how many hours I could run one of them in the evening from a Group 27 battery before its flat?
If I run the fan on less than full power is it drawing less 12VDC power, or is the controller drawing any the fan doesn't?
Surflo says the fan draws 4a max.
There is electricity in the area, but I'm thinking it will be too far to run an extension cord to a charger for a daytime recharge.
