We have a '92 Toyota Winnebago WT321RB (21 foot, Class C).

It has space for one (12V) battery only. We are wondering if anyone with one of these 'toys' has somehow managed to change the size of the battery compartment so that two 6V batteries can be installed.

Thanks for any advice!

what are the measurements of your battery compartment?

how much weight can your battery compartment handle?

look at lifeline agm batteries. they can be mounted on their sides for clearance in tight battery compartments.
i got mine from bd batteries on line. they have been working well since 2007.

they are kinda pricey,

but will last at least 10 years if not deep cycled often.

The inside measurements are: Width - 8.75" Depth (front t back) approx. 12"
Height: - 11.75"
I don't believe those particular batteries are available here in Canada, and yes they are very expensive and would be more so here as we are subject to what I call the GCRO (Great Canadian Rip-Off) plus ridiculous taxes.
Not sure what the weight allowable is, but suppose it would be in the GWRV or whatever it's called (axle weight restrictions).
If I can figure out how to post pictures, I will send one or two.
Thank you for your help@

Another option is Gel batteries, which do not outgas or leak acid, and are approved for indoor use without special precautions. Get a marine battery box and bolt it to the floor. They are very expensive (about twice as much as a normal deep cycle) and have about 20% less capacity per pound.

You might be able to fit two Group 17HF, 21 or 61 batteries in there, but I don't know if those even come in deep cycle. Or a single Group 27, which would just *barely* fit, and probably get you the most AH.
