We have been full time in our 2015 328 TS. For what it is worth...
Does the 50 Amp power keep the engine battery charged?
I do not think the 50 AMP power will charge the engine battery. There is a swith on the dash "BATT BOOST" that you can use to jump start the engine battery from the house batteries if the engine battery become discharged.
Can I use the Radio while parked or do I need to start the engine and let it run. If I do start the engine, do I need to bring the slides in?
There should be a "RADIO" button on the dash that will allow you to use the radio while parked without having to run the engine. You should not have to bring in the slides in order to start the engine. Just make sure you do not drive with the slides out.
I see to lubricate the jacks every two weeks (we're on the Gulf Coast); I assume I can use any oil on a rag to do it.
This is new to me. I hope someone else will reply to this question so I can learn.
Do I need to unplug from shore power to run the generator to keep it exercised?
I do not think so but there are more knowledgeable people on the board that may be able to answer better.
Anything else you learned the hard way that could prevent me some heartache?
Use plenty of water for the black tank and keep the valve shut until you need to dump the tank. I learned this the hard and expensive way.
I hope you have a great experience being full-time.
