I was considering buying the NOCO Genius10 but noticed the battery capacity rating for the NOCO is 230Ah. What does this mean for my 6 volt AGM batteries rated at 250Ah? Is the NOCO underpowered for my batteries? Will it still fully charge them?

    Should still fully charge them, but at 10 amps, it’ll take quite a while if they’re fully drained.

    In addition to using the NOCO in a pinch on stormy days or overnight when boondocking to charge from my TV's 120V 10Amp inverter, I thought I would be ahead of the game to also be able to use the NOCO to recharge from a generator directly to the batteries.
    RE the generator option, I was under the assumption that the charge rate on generator or shore power through the 30 Amp receptacle and onboard converter is limited to around 4 amps based on some of the other threads on this forum. If I am wrong, is the charge rate through the Tab converter greater than 10 amps?

    The charge from the onboard depends a lot on the state of charge of the batteries.  The greater the state of discharge, the faster the initial charge.
    This is what I got from my 2020 TAB400 (before I modified it):

    I cannot find any details regarding the NOCO charger, so I cannot comment if it would be better or worse.

    @rh5555 thank you for the info about the onboard converter.
