The battery box on my 19CCD was in the tongue. IIRC the Classics slide in from the front thru 2 doors. Not the same set-up.

On the CCD, I removed the hinged top of the battery box, made a 1.5" aluminum spacer that was painted grey to match top in the same footprint of the top flange, riveted that to the top flange of the battery box and then re-installed the hinged cover to the top of the spacer.

So, with 4 GC2 batteries onboard, can someone suggest an ideal charger?

Also, I wanted to get a basic "Starter" Solar panel to keep the batteries topped off... I dont want to get into the whole charge controller just yet... Maybe a 30W?

Another simple way to increase the depth of the box is to again remove the door hinge and then us pressure treated 2x2 wood cut to fit around the top of the box rim. You can screw it down from under the rim. Paint it to match and then screw the door hinge back on top. a simple slot or gouge sawed on the inside of the opposing wood spacer will allow you to lock down the lid.

If I was using 4 GC batteries in two strings, I would consider a Perko type battery switch so you could isolate either string or parallel them when you want to. Cost is about $30 at some RV dealers, most marine dealers, and on line. By putting them in two strings, isolated, you can use them like a propane tank system, run one until it gets low, then switch to the other. It also makes for better charging, one string at a time, rather than two strings in parallel.

I think a lot of the Progressive Dynamics PD 9200 series of converter chargers. Probably a 9260 would be a good one for you to use, but even a 9245 would work, especially if you charge one bank at a time, which I would recommend.

For solar, my opinion is you are just wasting your money if you don't do it right to begin with, but that said, for inexpensive systems, the Harbor Freight 3 panel system is fairly well made, and each panel in the set is 15 watts max, or 45 for all three. Cost, on sale is about $150.

The best (again, my opinion) charge controller for the money is the Xantrex C30 series, which, without fancy monitoring only runs around $100 and is a high quality, well made, well engineered unit. I do volunteer solar work for the Forest Service in my area, and have used them extensively, and never had a single problem.

Well.........
I did it!
There are 2 Costco GC2 batteries in my garage.
Both Manufactured 01/12 and $89.99 each.
I marked them A and B.
Tested them, and A was reading 6.37V and B 6.35V.
Linked them and put them on my Battery-Minder Charger at 8A.
They warmed up at 14.25V @ an 8A charge, and after about 4 hours, the charger detected they were good, and dropped off to 13.2V.

Here they are...


Fresh from Costco..

Battery A


Battery B


I then charged the with my Battery-Minder for 48 hours, and let them rest for 24 hours..
Battery A reads 6.47V
Battery B reads 6.47V
Linked, I am reading 12.94V.

Just an update, and a few questions...
The two batteries have settled at about 0.02v different.
Is that ok?

The GC2's weigh in at 63lb each, so 4 of them is close to 260LB!
Add the Motor battery at 40lb, and we have 300lb hanging on the slides..
Then adding teh weight of the modified drawer, and we are deep into the slides rating of 500lb, and over their 300lb "Mobile" rating.
I am looking at what to do abbout being sure this will work...

Started work on the mods needed to the battery tray..
The floor was too shallow and badly rotted.
I am dropping the floor, and moving the divider/support over to be in a better place.. somewhere in the middle, where it will not interfere should I decide to go from the planned 4 x GC2's to a possible 6x GC2's.

Pictures will tell the story...
Original setup...


Closer inspection...



Its going away...
Drilled rivits out...



Cutting rusty floor out..







Planned footprint.

Ah, that battery drawer looks so much like the one on my 83 310. It brought back memories, but fortunately, mine had no rust problems, nice solid floor. Your rebuild with the dropped floor should work well. I think you are pushing the weight envelope with the possible 6 GC batteries, but 4 is a good idea.

Have fun!

Some more planning, and measuring..
I made some choices.
The floor will drop 2.5", and the divider will move to the center to make best use of the space, and to support the center of the tray.

This way... if I moved the Engine battery somewhere else..
I could fit 8 X GC2's in here!
Thats 520lb....

So, yesterday, cut out the divider...



And the Toolbox section lid..



Plan to put the divider back in the center, but will have to do some repair work all around...



Including moving the isolation switch, cos the diveder runs right thru it!...


Scrap..

For longevity I would pick the GC batteries. Are you planning to go off grid and don't want to use your generator? gc batteries can do it all in combination with solar collectors, so you have to figure what they need to run and how much solar power you will collect and save. While traveling the motor will generate more than enough 12 v to store for lights, run the refrig and microwave, when parked you will need a large bank of solar collectors and gc batteries to store all the power the unit can use.

Thanks Dave.
Yes, all the reading i did told me they were a cost effective and better way to go.

The defining moment is when you put the 2 GC2's next to one another and then compare that to a single Group 27... the sheer mass and volume, and weight tells you that the capacity is there.

The shorter term plan is to get 4 x GC's, and have 2 at each end of the tray to spread the weight load more evenly.
I would love to go for it and get 8 x but money says no at the moment!

Longer term plan to to add Solar and be able to exist off the grid and minimise or eliminate Genset use!

Sheer Mass, and Volume is the key...

How does a Group 27 compare in size/volume with 2 x GC2's?

Like this...
