Adding a second battery?
My new to me TT has a 12V Interstate deep cycle marine/rv battery, spm-24. Looked on line and it offers 140 min. at 25A and it looks like I'm could use as much as 10 amps an hour without the furnace ...

Up to this camping season I have been using three each 85AH Interstate 12VDC batteries (TOTAL 255AHs) in my battery bank. My concept for camping off the power grid is to decide what all I want to run from both 120VAC using an INVERTER and 12VDC direct connected to the battery bank. Then I need a battery bank large enough to handle this load for just one day/night camping run.
At 8AM the next morning I will connect my trailer shore power cable directly to the 2KW Honda generator 120VAC receptacle using a RV30A-15A long adapter (WALMART). This will allow my on-board SMART MODE Charging technology converter/charger to re-barge my battery bank up to its 90% charge state in around three hours. Now I can do all of this all over again for the next day/night camping run... The only problems I sometimes run into is the camp ground does not allow enough time for me run my generator for that long of a continuous time so I have to split that up in a couple of allowed generator run times during the day. By early evening I am ready to go with a good 90% charged up battery bank.
We have been doing very successful for the past few years camping off the power grid and get to run just about everything we run at a regular electric camp site with the exception of air conditioning and high wattage microwave. Also when it is cold the propane fired furnace and its 12VDC high current fan makes it very interesting to keep up with the battery drain over night.
It does take some planning to be successful about it.
