I just acquired a 1988 Foretravel 3600 ORED It has 3 batteries that I have found. 2 under the steps and 1 in a rear/side compartment' They all look similar in size 8D but are they all Deep cycle? I would assume the 2 under the steps would be house batteries and deep cycle but what about the rear/side one? Thank you I look forward to a whole new learning experience
The engine batt can be any batt with 900 plus cranking amps . One good batt will start the Cat 3208 in most climates.
The 2 under the steps are usually deep cycle.
Some buses had one of the under step batts connected to the rear battery for 2 start batts.
Autozone has a couple of deep cycles that can work or you can find the correct 8?d
Another option for the house batteries is PAIRS of 6VDC golf cart batteries wired in SERIES= 12 VDC battery.
They ARE deep cycle and usually less $$ per amp-hour than deep cycle 8D's.
And, yes, most 8D's are start, not deep cycle batteries.
x 2 what Mike and Brett said. Keep in mind that lead acid batteries need to be watered whereas AGM's and lithium do not.
I used the 6v golf cart batteries for years as house batteries and you do get more amp hours for your money. They also make a watering system that makes watering them easier.
How you plan to use your coach should be a consideration. Will you be doing a lot of off grid camping? Does it have solar panels? Are you planning to add them? You may want to consider lithium.
This one works for small loads.
