Yes, you have to consider power factor when running on a generator, but that wasn't the point of listing the power. That was getting a sense of $/A for the PowerMax vs the Meanwell power supply.
It does seem like the way to go is with the Powermax, for best bang for the buck.
I am quite certainly overthinking it. I enjoy doing that, it's quite fun for me. :) I'm definitely not a fan of the PD though, as it's fixed to 14.4 (or 14.8) with no adjustment for temperature, and no equalization mode.
I will for sure be charging these batteries at freezing temps or below. At 32 °F, the proper charging voltage for a set of Trojan T-105s goes from 14.82 V to 15.58 volts. Charging to 14.8 volts simply will not get a full charge at these temps, and not charging to full is bad news for storage, especially when the lows get to around -15 °F for a night or two sometime during the winter.
It's also a fact that I'll probably charge them when it's 100 °F in the summer. Now the proper charging voltage is 14.44 V, so 14.8 volts would now be overcharging. Hence my requirement for a temp compensated charger.
Yes, as BLF13 suggested I could remove them and charge them at home, which would remove the requirement for temp compensation, but even being young, it doesn't sound like a lot of fun to carry two 62 pound batteries from my camper to house and back again once a month or more. They will stay on the camper.

You might be overthinking the whole process. Just swap out the junk converter (WFCO?) for the PD9260-14.8 and your batteries will be just fine lasting a decade+ with proper care of the water and charge level. All automatic plug-&-play and plenty good in all conditions.
