Am considering adding a second battery to our TT. Also would like to add a switch. Have some questions.
I understand how to wire the batteries in parallel. Since I am not depending on a battery to start an engine like with a boat would I be better off to wire the batteries in parallel and put a disconnect switch between them and the TT or if I use a 4 position battery switch (off, 1,2, both) can I use that instead of wiring the batteries in parallel?
I guess maybe that is my real question, does a battery switch on "both" serve the same as if the batteries are wired parallel?
My old RV had a switch like this but had been wired with 2 current blocking diodes positive side of both diodes hooked to load (house side) and then negative side of each to bat 1 and 2 respectively. This allowed both the batteries to charge but not drain in any position, but once the battery was selected the power could flow freely in both directions on that battery.

Thanks for the replies, quick follow up. I am assuming (dangerous I know) that if I am using a switch and have it set on "both batteries" for example if the convertor is running then both batteries would be getting charged, correct?
