I need to replace two 12v batteries in my new to me 24' bumper pull. Right now it has random batteries that the PO (trailer park resident) threw in there and they're toast. They're in universal plastic battery boxes on the tongue between the propane tanks and the body but I'm not opposed to building a new non shitty looking box to fit whatever. What's the go to battery for this sort of thing?
 
I go to Napa and get two of the biggest Marine batteries they have. Should be out for ~$300 plus tax and cores.

If you want to get fancy, look at Trojan Batteries.

Two batteries each wired in series as in the first picture makes 12 volts, then those sets of two batteries are wired in parallel so you have 12 volts with four batteries
 
Dry camping or Boondocking is camping with no hook ups. I don't like RV parks, don't like very many people for that matter. Like to camp away from others except for my group. I only stay in RV parks when I don't have an alternative or its going to be hot wherever I am going and I want to run the AC at night.
 
I understand what dry camping means :lmao:. I'm just stating all the noobs that call it "boondocking" have fucked up the lingo all us old timers use. :flipoff2:
 
Thanx BDK, That's a great bank setup.

I have 4 6v's. Go 6v like everyone has already said :grinpimp:
 
Golf cart batteries, tried and true. We have 6 in the nose of our 5th wheel, it looks like the trunk of my neighbor's low rider. Once you get the batteries in, start reading up on chargers/converters. The ones that come in most RVs are junk and make it hard to properly maintain the batteries. Also make sure to check the water level a couple times a year.

Weird, on my travel trailer tips n tricks thread, i was told 6v are old tech, just go 12v. So I bought a big ass marine deep cycle at Costco and it works fine.

the largest advantage of 6v batteries is electrolyte.

there's simply more electrolyte because there's less cells in the same size battery.

and more electrolyte means, longer battery life in terms of replacement time, but good condition 12v will provide the same amp hours... but need replaced more often?

is that right?
 
Aside from the physical difference between 6v and 12v batts is the ability to depp discharge the 6v cells with minimal damage. Even a $98 GC2 6v from Sams is rated to discharge 70-80% where MOST 12v batts are rated to max discharge of 50% and AGM's are even severely damaged below 50% DOC.

Post up the 12v batteries you are considering and lets compare stats.

I have 2 Duracell 6v GC2's from Sams total cost was $212 and with 400w of Solar I have near unlimited power when camping.

This is the biggest thing people overlook when they upgrade batteries and in some trailers, the hardest to upgrade depending on where its located

they also have, generally, more plate surface area, so they don't sulfate as badly when discharged so deep and they can come back more easily.

bottom line is that if you build a larger battery with less voltage, it works/lasts longer because you simply have more shit in there that makes the battery work.
 
Even in 6v battery world not all are equal. It is said the Trojan t105 cn handle twice the discharge cycles over the t125(higher cap).

Also for the electronics, go Victron and dont look back.
