Thanks everyone for your input on this. It appears to me that the only real difference between the Iota and the PD is the frequency of the equalization mode.
The PD will equalize every 21 hours of non use of the battery.
The Iota will equalize after every 7 days of non use of the batteries. This fact has me leaning toward the PD as my trailer is rarely plugged into shore power for more than a few days before it gets unplugged and hauled back to storage. I know already that the blinking LED on the pendant would bother me when camping. But I imagine I can just leave it in a cabinet or otherwise out out of site so I don't see the blink.
@Pianotuna: I agree that SiO2 batteries would be better suited. But they're still a bit too expensive for me. The 90 percent is what I'm targeting while I'm out camping as I know that the charge time from 90 - 100 can be long. In the past I really didn't mind long generator run times out in the desert. But lately I want to just get enough charge back in so that I have the heater overnight and get back to the quiet. The trailer gets plugged in at home for a day or so to get the batteries up to charge before storage.
