I have a 1993 Class C. I am reading of the advantages of going to 6v over 12v. I have found a guy locally that has 4 trojan 105 6v batteries that are one year old. I am considering these as I do alot of winter boondocking while snowmobiling. I would build a sealed battery box in one of my storage compartments. Should I wire in a switch for 1 set or both sets of batteries, or just wire them all together?
Thanks

Without reinforcing the storage box, I would worry about the load Marvh

Do you do so much boondocking that you need 4 batts? I added two 6's to my existing deep cycle 12v and can go for a good week without worrying, then run the gen for an hour if I run short. I'm not sure about your wiring setup, I put a disconnect on the 12v and put both 6's together with no switch. Be careful about the weight, those things are heavy and the compartments are not strong. I reinforced the bottom and vented the area.

I don't guess that I need 4, 2 will problably do as I have a genny as well. I could keep the other 2 as backup incase I need them. I don't have room under the hood for the two 6 volts so I am thinking of adding them to a compartment in the back and building a battery box. Do I need to worry about voltage drop?

Couple of things...
1) I hope that by "6v over 12v" you mean the use of two 6v batteries wired in series to give you the 12v that is needed in the RV.
2) Year old batteries may or may not be worth the money. You would want to check them, to see that they are in fact able to hold a full charge...or they really aren't worth the conversion and efforts on your behalf.
3) If you do decide to go this route, you don't need to seal the compartment under your coach. But you will want to seal any wires or openings that go up into the cabin...You will also want to put in some vents, low, on the side of the compartment, to help get any fumes (which will be heavier than air) out of there.
Here's what I have:
12Volt system
4) I would wire them all together, as that will give you the most bang for the buck, but you may also want to really jazz the system, and install solar panels to keep them charged. I have a system like that, but bought it with the RV, so don't know enough about it.
You will want a more powerful inverter.....or do you just plan to run the 12v system for an extended weekend.
5) One recommendation with using the storage compartment.....make some sort of slide shelf for the batteries, so that you can pull them out to inspect and service them when needed. I've got to make one for mine, eventually.....
Good Luck....but check those "used" batteries...they may not have much life lift in them, if the previous owner was abusive to them...or let them drain down to often.

What are the advantages of two 6V batteries over two 12 V ones?

Two things, If it was me I would just go to sams and buy new they are good enough. You need to use a battery switch just incase you have a short just one will do.

Hi seth25,
I'm not reading the same posts as you. What matters is amp-hours. Surf here for lots of information.

and click on "Battery Selection".

If you put a switch in when you store your MH you will be able to cut off those two batterys to prevent any draw. 2 if you get a short or want to work on the system you can cut it off. 3 if you are in a spot for a short time and want to charge batterys just turn off the 6 volts and use a differant battery charger.
