Dave, if your F350 has the upfitter switches perhaps you can use one of them to toggle the charging circuit.
we will be custom ordering a 2020 F350 so we can pick any set of options….
reading the thread above I’m sad that it may well not be a simple plug in for our new pop up camper …. :-/
a question about the upfitter switches… where does one tie into them? in other words – where do any wires need to be run, to use the switches with those wires?
