My suggestion if you're not already doing it is to run the generator every day, maybe even morning and evening if you are using lots of electricity. Don't wait until you have deeply discharged your batteries. Deep discharge is bad for lead acid batteries, much better for them never to get below 50% state of charge.

Hi, problem is solved 2 new batteries...I do have 260w of solar panels but no good here, no sun too many trees..My generator is a 3100w champion. I've only been on shore power 4 times in 4 years so I guess that makes me a boondocker
Thanks to all for their inputs..

I posted a review of the Firman Dual-Fuel generator I recently purchased. Here is the link for the review:

Also, in my mods, you will see my write up of my LiFePO4 installation and all that was needed to make that work. One other option for charging your battery is to put in a battery isolator in your tow vehicle, run a dedicated power circuit, and get a DC to DC charger. I installed a 20A Renogy unit for the LiFePO4 battery, but it can be configured for use with PB-Acid batteries also.

When you buy new batteries get two 6V golf cart batteries and connect them in series. GC2 size. If you do a lot of of boondocking this will provide you with the most capacity short of going to Lithium batteries. Beware of your tongue weight however. 

I agree with the other suggestions regarding keeping you batteries charged. Get a small generator and also solar if you camp in sunny places. Several considerations on the generator:  do you want to use it for running the air conditioner or not? Do you want it to run on propane or gasoline? Do a search on the forum for the pros and cons.

Some tow vehicles do not charge well through the 7-way. In that case, you may wish to use a set of jumper cables to connect directly to the battery from the TV's battery to charge. That will be faster. Even a small generator like the Harbor Freight TailGator will work better for charging the battery although it would not be sufficient to run the air conditioner. If solar isn't a good option for your location, and if using the TV as a generator for charging isn't desired, then a generator is your only option. Some places only allow them for limited times such as a couple of hours in the morning and a couple of hours in the evening. The TailGator is fairly quiet for a non-inverter generator from what I recall when I heard one running. Otherwise, look for an inverter generator such as the ones from Honda, Yamaha, Champion, or like the Firman generator I just recently purchased from Costco which is dual-fuel (gasoline or propane) capable.

If you are going to be a serious boondocker you need to look at recharging methods. You can look at solar and TV methods on the cheap. Run your TV and hook up your 7 way. Let the tow charge the batt.

Check to see that your acid level is full.  Top off with distilled water.  Expect 12 to 24 hours for a full change.  How old is your battery? 

See section II in this link.
https://www.trojanbattery.com/tech-support/battery-maintenance/
12.6V is no more than 90% State Of Charge (SOC), *IF* the battery has been sitting unused for 6 to 24 hours. 

Bulk charging voltage should be 14.6V until the current drops to 1% of 20-hr rated capacity.

They do go bad. I have a 2015 with original batt. Not a big boondocker. Easy to test battery. No shore power eliminate converter.
