running two chargers
Here is a technical question. Let's say you want to charge your house batteries on your RV quicker. If you have two 12 volt batteries in your battery bank would you charge that battery bank quicker ...

I feel like it would be much less of a hassle to just upgrade your converter/charger to a 75amp/100amp model. No Mickey mousing clamping or disconnecting batts. Just my 2c.
well, since I have a 2000VA generator, it will NOT run a 75 or 100A charger. so, I have a 55A charger in place of the WFCO and a 65A in the pass through. when only on one generator, on goes the pass through 65A. when I have shore power or two generators then I crank them both on and get 110A or so for quite a while.
So, there are reasons to have two chargers rather than one.
and there is no mickey mouse stuff, I just turn one or the other on or both on. both are connected to the same battery bank in parallel.
75A on 15A line, 1260W.
Any good?

look at the current draw which they don't specify, not the watts. Since most converters have pretty bad power factors, the actual current draw is higher than the watts calculation would indicate. Now powermax does make some power factor corrected converters. but they are the only one with a 100A power factor corrected converter.
In reality once you take into account the terrible power factor of most all converters, the current draw is well over the watt calculation rate. my PD65A measured draw at 60A is in the 1300VA range, comfortable for the honda 2000. IIRC The 75A has a 20A plug, won't even plug into a 15A circuit because the VA draw is so high and is marginal at best with a honda 2000. anything more and it's overload time.
