Second battery

Looking to add a second battery to my 2019-2506. Any feedback on what batteries are good.

questions...

true deep cycle ( more expensive) or dual purpose Marine?

6 volt or 12 volt?

group 24, 27 or 31? ( size makes a difference)

best battery prices on some types at Sams or Costco, but not all types are available there...

If you want two batteries, it is best to match them in mfg date and type for the longest life for both of them.

Trojan, but they are $$.

If you are mostly camping with full hookups you really don't need 2 batteries. If you need 2 then as suggested above they need to be matched or just use 1 until it is about 50% & then switch you wires to the other battery (using just 1 battery at a time). I use 2 6 volt batteries from Sam's Club which are 1 year old. I won't know how good they are for another 4 years or so. They are very heavy to move though.

US Battery is similar to Trojan. Smidge cheaper.

Lead acid batteries are about weight. The heavier, the more capacity, nearly without fail.

Because you have plenty of room 2 batteries should not be a problem. Please post what is on there now. If it’s a group 24, with any age on it you are better off getting 2 bigger batteries. A lot of people here use 2 6volt golf cart batteries in series to make 12 volts. Myself I use 3 group 31 12volt batteries that are a compromise, not a true deep cycle but the price was right ar $79 each IIRC. A group 31 will barely fit in one of those black plastic battery boxes for a group 27 battery. Jay

You don’t 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.

Good luck
