Re: Flooded cell deep cycle 8D battery

My thoughts, which are the same as John's (above), but I use a lot more words. (English major...)
Flooded batteries can work fine in RV application, BUT, they require a lot more attention. You must monitor the electrolyte level religiously, and this is a real hassle in some coach setups. My '93 U280 has the 2 batteries stacked one above the other in a VERY tight space, making it almost impossible to check/add water to the "rear" cells on both units. This was one of my prime motivations for switching to AGMs, not long after we bought our coach. To me, the extra expense of the low-maintenance AGM design was well worth it.
There are "watering" systems on the market that have tubes that plug into each of the "check" holes on flooded batteries. They will allow "semi-automatic" filling of all the cells simultaneously from a single source. I have never used one of these devices, so I can't comment on their effectiveness, but (if battery access is a problem) you might want to consider something like that to help ease the service routine.
A high quality, "smart" battery charger is essential to the long life of any type RV battery, but especially so with flooded batteries. Over charging, which is common with older "dumb" battery chargers, will quickly kill a new battery. If you are still using the original charger on your '95 model coach, you really should consider upgrading. Your batteries will thank you.
