Generally, AGM's do self discharge slower than Wet Cells, however we are talking months here, not days.

If by "holding a charge" you mean that when boondocking you have to charge 'em every day.. That is normal and changing to AGM's will only flatten your wallet. VERY FAST

Now if were talking about parking for months at a time I think that is where AGM's would be better (Provided you disconnect negative cables from the batteries before parking, or right after (As in a few minutes)

SOME AGM batteries are kind of interesting, Lifeline specifies a re-charge rate of 30 to 300 percent capacity. Most battery makers say "No faster than 30% and Trojan, says even slower (like 10%) You don't need to water AGM's. you rarely need to equalize.

But as for providing amp hours of power (Watt hours if you like) running your furnace, inverter, and such.. No advantage at all.. Flooded wet cells give the best bang for your buck
