"Pretty soon we'll be talking real money" :)
I can still do the truck inverter trick as my second generator to run another 35amp Vector. (I have three of those plus the 40amper from when I recharged that way) That would give me 185amps to start off with. (100, 40, 10, 35)
My plan is to have each bank need a recharge on different days so I could just use the 100, but I can see how I would give the other bank some recharge since the gen is running anyway. It would all depend on how long it is before going home and how far down the batts are. With the new 30% limit on the 6s, that gives more wiggle room on that.
Yes, if the 7355 ever dies (no sign of that) I would be looking at the 75amp PM to go in there. I calculated that my wiring upgrade (using some copper water pipe as wire on the neg side if you remember that thread) can handle 75 amps to the batteries up front.
