Thanks for the great info, everyone. I'm heartened that several of you think that I will be able to get by with ~4 hours of generator use per day, and that I shouldn't expect/have to get the battery back to 100% each day.
Is there an advantage to breaking up the 4 hours of generator use into 2 x 2 hour segments?
I certainly won't rely on the engine alternator, but I hadn't thought about the fact that I can run the truck heater to warm up the camper at the same time--that is also an advantage.
I'm not sure exactly which converter I have (it's installed under the dinette, which now is the platform for my dog crates, so not really easy to access unless absolutely necessary). My owner's manual is for MagneTek 900 series, but there are several models listed. I did check the voltage on the battery when it was charging, and it was 13.6V.
There isn't room in the current battery compartment for another battery, without some modifications, so I'm not sure how that would go.
KD4UPL and BFJ13: you recommended a adding a portable charger. Wouldn't I need to be plugged in to shore power to use one of these?
I really appreciate the input. It does sound like you guys think I can make it through my event with what I have, just will require lots of generator use.
