Battery for 94 Fleetwood Southwind

[GuitarLefty]

I've got all of the manuals, operators guide etc
There is no mention of which battery to replace
The existing battery is a marine battery with 720 cold cranking amps, just no idea if this is correct,
The engine is the 230 hp Cummings diesel, thanks

Starting battery or house battery? Either way, look at the label and it should have a 'Group Size' number. Match that and the Voltage (12v or 6v, most likely 12v) and you'll be good.

If your looking to replace the, engine start battery, and it is a single battery set up , Dodge P/Us of your vintage used a 1050 Cold Cranking Amp battery. If there is a 720amp marine battery in there , then some one just dropped in what they had laying around to get it going.
If this battery is for the house/coach 12v systems, you want to get a Deep Cycle battery not a marine. Marine batteries are designed to stand the pounding that being bolted down in a boat hull gives them, and at 720 amp to start a small boat motor, not your diesel.
Measure up the battery tray, length, width and height, go to a battery/auotmotive supply, and get the Most CCA for the start battery that will fit,if your looking for the deep cycle ; coach battery; the same applies. Bigger is better.
Deep Cycle batteries will tolerate being run down,re-charged, more often than the other types.

Sorry, 93 was the last year Dodge / Cummins used a single battery to start, in 94 they went to a dual battery set up.
Can't trust anything to memory anymore.
If the battery listed for a 93 Dodge P/U with Cummins will fit, for your start battery , that's the one to get.

Starting battery, but the house batteries are original and could stand replacing I am certain. The wiring on top of the house batteries looked pretty elaborate, thanks for the information on the start battery, I thought 720 to be undersized for CCA's - I will pull the start battery and take some pics with my phone of the 2-house batteries and replace all 3 at the same time, I appreciate the help

BTW - I've read a few post about the 230 hp Cummings and just wanted to express my thoughts. The engine along with the Allison 6-speed tranny work marvelous on this particular coach, the weight is under 20k loaded and it performs on the interstate without a problem, moves up hills great and we don't have many mountains around here. The engine has 39k original miles on it, and although newbies we are having a blast !!!

Get out , and continue to enjoy your rig, at 230hp the Cummins 5.9 was 99.9% reliable. Moving only 20k down the road I'd say look to trade it off at about 400,000 miles . Safe Travels
