As others have said there are no "dumb questions" only the one you didn't ask, and we learned that in first grade, well most of us did anyway, so just ignore the rude comments from the "experts". It's too bad as the majority of us come to this forum to help others and learn something for ourselves. Nobody knows it all.

You mentioned you have a generator. If you have a generator you can just run that in the morning/evening to bring the charge up on your batteries, and make your coffee/breakfast/ watch tv while it is running. We run ours about 2 hours in the morning and two hours before quiet time at night and that keeps the batteries fresh and everything operating when we are dry camping. If you have the inverter or can add one, that is a nice option as you can then watch TV when you don't have the generator on, late at night or after quiet time ect.

Idling truck for 15-20 minutes will do NOTHING for charging your trailer batteries.

Charge line for truck to trailer is SMALL and LONG
Alt. on truck is monitoring trucks batteries which will be charged so little charging to trailer.
Idle speed very little charging
Trucks DC Charge line to trailer is for 'maintaining' trailer battery while in transit and due to issues above can only provide a minimal charge over many hours of travel

SO NO.....truck is not the source for 12V DC
And an idling truck is almost as annoying as a generator.

Direct answer to OP question, yes you can run the truck for a short time each morning. (Especially if the truck is mechanically in good enough shape to tow your TT around.)

However I agree with others on this forum in two regards.

1. Asking a question, any question, is what this forum is all about, so there are no real dumb questions. Ask away, and most here will try to answer. Some may ask for more details, and everyone has a different amount of ability to ask their questions without sounding arrogant, or dismissive. Some are pretty good at asking for more details without causing any negativity, some not so much.

2. There are most likely a couple better means to the ends you are looking for. In other words, what you are trying to do may be doable as you questioned, but there are most likely better solutions. Several have been presented already.

Have fun. Good luck.
