I just bought a beautiful 2004 Adventurer 33V on the Workhorse chassis.
The house batteries are toast. The ones in there are Napa 24DCM.
Question: What group size comes standard, and will a group 27 fit?

Thanks,
woof

The biggest ones that will fit. Can be tight, Take measurements. Ours is currently sleeping cover with snow so I can’t check.
BTW… you’ll love this coach(especially on a Workhorse chassis IMHO)!!!

I managed to stuff 2 group 31s in beside the chassis battery on our 2008 Adventurer, so if you try hard enough you can do it also I'm thinking. Are yours under the steps?

Strip all 3 batteries out and also the hold downs. all 3 batteries go in sideways (or across).

Because we dry camp, I also managed to install 2 more 31s in other areas.

Now would be a good time to consider either 2 or 4 GC2 sized batteries, either lead acid (best bang for the buck) or AGM. Others would even say go lithium.

Lots of info on options here at irv2.com

Like this thread.

And definitely don't worry about what it came with. They were whatever Winnebago could buy the cheapest. (Bought mine new, forgot what it came with. They only lasted a couple years. Have had 4 GC2s for like 15 years now.)

I have four 6 volt batteries in mine

I recommend 2 27DC batteries

6 volt lead acid, definitely best bang for the buck.

I had two group 31s in my 2013 Adventurer 37F. Worked great, but next time I would go with 6v golf batteries.

Unless they redesigned the step well it should take 2 Group 31 batteries with a little effort to shuffle them into place.

Seriously consider upgrading the converter charger though into something like a Progressive Dynamics with the Charge Wizard which has a true float cycle and automatic desulfate mode. The Magnatek they commonly put in back then has a reputation for over charging and cooking the batteries to death.

Agree with updating the converter/charger.

If you stay w FLA I would say a pair of 6V GCs are your best bet. I used them for years in our 2003 Adventurer.
If you consider AGM you could go with either the same (2) 6V GCs or a pair of 12V GP31s if they will fit. They should be fairly close yo the same AHs. The benefit is if you have a batty failure you could run with one 12V GP31 until you get replacements not so w 6V you need both.
Both East Penn and Trojan confirmed with AGM the deep cycle performance is the same w GC or GP31... not so with FLA. If you look at AGMs most mfg spec both AH and CCA recognizing suitability for either application.
