Ooh, wrong approach, though a common one.
Most generators have a battery charger output. It seems that no matter what size generator you have, the battery charger output will charge at 8 amps max. And sure enough, at 8 amps, it takes a long time to charge a 75 A-H battery that is down to 50% charge. A better idea is to plug the TM's shore power cord into the AC outlet of the generator. This fires up the TM's converter/battery charger, which can charge the battery much faster than 8 amps.
I have no idea why gen manufacturers think an 8-amp charger port is a good idea, but they seem to.
