Our rig does have a solar panel. We do like to boon dock, but are still relative newbies at RV life
Thor tech support said just go to Walmart and pick out your favorite type 27 battery. Easier said than done. Our local store only carries the Everstart and it will not fit our space. If I order the Mighty Max (which has a large number of poor reviews) via Walmart.com it appears to not be returnable if it doesn't fit well either.
So, recommendations please - preferably deep cycle, long life, maybe AGM.
Thanks.

Common old sizes battery group 22, 24, 27, 29, 30 and 31 are all about the same width and height. The difference is in length; group 22 are 9" long and the group 31 is about 13" long. The heavier the battery the more amp-hours. A good place to start until you know what you want is: <https://www.batterystuff.com/kb/tools/bci-battery-group-sizes.html>
Walmart sells a complete line of combination batteries labeled as Marine/RV Deep Cycle in the EverStart brand which I think are a great value for a 4-5 year battery life. I have two of those in the group 29 size which barely fit.
They are flooded, but I have a watering system. They will probably outlast me. Yes Trojan have a longer life the Everstart, but I will be dead or have a new coach in 4 years. AGM batteries are better but cost twice as much, but they can be shipped UPS or by Amazon..
