You donít mention your application. If you occasionally dry camp for a day or two, any deep cycle batteries should suffice. If you plan on more extended boondocking you should consider going to 6 volt golf cart batteries wired in series (12 volt output) for the additional amp hour capacity. I have used a pair of Trojan T-105 6 volt batteries wired in series for years and had a good experience with them.
There are a couple of things to consider when adding an additional battery.
1. How will the additional weight impact your GVWR and tongue weight. Addition of a single 12 volt pair of 6 volt batteries will add a significant amount weight.
2. Additional battery box(es) will be needed. The 6 volt battery will not fit in the 12 volt box.
3. For wiring 2 6 volt batteries in series you will need a heavy gauge wire to connect the positive and negative terminals together.
