Deep Cycle Battery???

The biggest downfall I see with that battery is that it is a "Maintenance Free" starting battery. Strengths, it will deliver high current without as much voltage drop as you will get with a deep cycle. If you wanted to run a high power inverter for short periods of time it might be a good choice. Most RV'ers however are looking for low to medium power demand, for a fair amount of time. they also tend to want to drain the battery down a fair bit, often to 50 percent SOC or so. Starting batteries wear quite quickly under those conditions. Last thing to look at is the maintenance free aspect. It's a wet cell battery, which tend to gas as you charge them, especially if charged at a high rate, or overcharged which often happens with the relatively low end chargers in most RV's. Life expectancy of this battery for RV use probably only 100 to 200 cycles depending on how deeply you draw it down. Depending on how you use it that might be a couple years. Many RV'ers kill their initial batteries fairly quickly learning the ends and outs of disconnecting when not in use, getting batteries fully charged, learning their charger overcharges or whatnot, so starting out with a less than optimal battery might just mean you're not quite so mad at yourself when you kill it.
