Is killing batteries three times too much?

After reading up on sulfate on and what kills lead acid batteries, I have learned some things. Firstly, I have been backwards on my charging routine. I always charge them just before I leave when I should be charging them as soon as I get home. Secondly, the converter/charger in my new RV is not going to be the best way of keeping them healthy. Finally, I should be able to extend the life of my current batteries by performing a desulfation procedure.

For the last option, I can buy the Black and Decker charger identified above which has some nice automatic features. I can make my own desulfation which may/may not work and may/may not burn down my house. Finally, I can buy the BatteryMINDER 12248 which probably won't do as well in recovering my current batteries as the B & D unit, but with the smaller form factor, I can install it in the camper permanently.

Still not sure which option I will take. I haven't stated a good fire in a while.

I think the most cost effective option is to buy the B&D 40 amp charger use it with your Genset to recharge when dry camping. When you get home plug in you single stage charger to top of and maintain the batteries untill your next trip. This way you have two chargers. Also what I have found is that my single stage charger will give a more complete charge once the smart charger says full. I know I can get several more days of camping if I use the single stage charger to float the batteries for a couple of days before camping.
