Charging house batteries

Parked in front of my house and the house batteries are low. What's the best way to charge them? Nothing is on in the rv. It's just sitting there.

Turn on the vehicle engine and let it run? **NO**
Turn on the rv generator and let it run?**NO**
Some type of trickle charger?**NO**
Extension cord from the house to the rv with a converter plug into the back. ***YES***

Also, the Bigfoot auto leveling jacks are down and won't work until the battery is at 100%. Then, apparently I have to unplug the interface cable.

What is the interface cable?

Forest,

According to one spec-sheet I found, your new coach should have a Progressive Dynamics 9260 as a converter. That means that all you need to do is provide it with 120VAC and let it do its thing.
Do not run the main engine to charge the house bank. There is nothing good that happens when an engine is idling.
Do not fire the coaches APU and waste the hours on it when you have shore power available.
Do not buy a trickle charger because the 9260 will be a trickle charger if you need one. Again, supply it with power and let it do what it thinks need be done.
If you run an extension from your house, just be sure that it is heavy enough for the job. 14AWG will work, but it can get warm. 12AWG is better and it is worth the expense. 10AWG would be better, but unless your house wiring is better than most, it would be heavy and have little benefit.

As to what is an interface cable, I can't help you there. I can think of about an half dozen answers that are probably all wrong.

Your converter will charge up your house batteries - just plug into your house (assuming you have a 30/15 pigtail that you can attach to your 30 amp cable)
