Wow. Haven't posted in a while. I have missed tapping into all the available wisdom here.With Covid and boarders closed, site availably has sucked around me.We managed two sites consecutively at a great campground. Problem is one of them has no hook up. DW says she only needs the propane fridge/ its DC power circuit. i'm converting to LED bulbs throughout, likely only a bulb two for a few hours each day. i guess there will be the DC holding tank pump draw for a few seconds now and then. Am i missing any other loads ?Question - i have currently only one new deep cell group 24 marine battery, (1000 crank amps 130 reserve capacity) no other useful info on the label. How far will this thing last with my minimal loads ?I am willing to buy solar, and/or more bigger batteries. However, will likely never use them again.Milwaukee tool offers an expensive power station that i could justify for use at work. However, it only provides 750whr before it also needs charging.If me. what would y'all do for a weeks time till hook up is available ?Thx in advance !Greg

I don't think your set up will last very long even being frugal. I use two golf cart batteries when I go fishing in the mountains. I have a Honda 2000 generator that I charge them with. They will charge with the generator just idling every day for about an hour. This works even when the heater is running all night with the temperature 19 degrees.

I have had very good results using a small 2000W gas powered inverter generator (Firman) from costco and before that a larger heavier Champion 3500 generator. Both had the RV receptable and standard 120 AC receptacle. With adapter you can use RV socket for 120 AC also. Also has a usb socket for charging phone and laptop. I also carry a spare 12 volt truck battery for use with trailer and truck as backup plus a small smart battery charger to charge batteries if needed. Each item is very small and weighs less than 50 lbs. For jumpstart emergency I have inexpensive but powerful lithium power bricks/banks that will fit in your glove compartment. They have worked wonders for me when I had starting problems. The brand of one of them is "Type 5 or S"In the quiet econo mode I can run generator for 8 to 9 hours on one gallon of gas.

If you'll have full sun, you could get a 100W solar panel + charger and hook it up to your house battery to keep it charged.With good sun (the panel needs to be shade free for most of the day), you should get around 30 Amp-Hours a day of charge for your battery from a 100W panel. Since you can keep your battery power usage to a minimum this should be more than enough.That 130 minute reserve capacity battery will give you around 54 amp-hours of capacity, but you can only reasonably use around half that without discharging the battery too far.

Get a 1000 watt generator to charge your battery

Well, without investing in any of the aforementioned items my only guess is possibly charging your single battery with your vehicle daily to keep it from going dead by the third day. When RVing off the grid it is all about replenishing consumed amphours back into your 12 volt reserves, takes a multi-pronged solution to be able to use your RV as if plugged into shorepower.
