Best way to supplement battery bank?
Hi, We're heading out on an extended trip of about 10 days, battery power only. No plug-ins, although I do have 2 T-105's and 230 watt solar to keep us going. We've never had an issue keeping cha...

You did not state what type of RV you have, but if it has a modern CO meter, propane detector and refrigerator, then they will consume about 30 - 35 AH daily. This is about what one of my 120 watt solar panels will put out in a normal day. You have very long days in Canada right now, so I am sure that you can collect some 100 AH daily in your long summer days.
This will be more than enough power to fully charge your batteries daily, unless you are using the furnace, or leaving a laptop run all day on inverter power.
You probably also do not need to run the lights much. The water pump draws 7 amps per hour, and can pump 2 gallons per minute, thus 120 GPH for only 7AH of power - 84 watts.
You will be fine without the extra batteries.
I would leave the truck running while deploying the slides, as they will take a lot of power for a short time. And then check the battery meter before leaving. If it reads nearly full, you do not need to idle the engine - the battery and solar provided plenty of power to run the slides.
While the slide motor uses a large amp number, a 60 amp motor run for only 1 minute is a total of 1 amp hour. Your battery will store 220 amp hours. . .
Have fun camping!
