So, can I make this wire-size mod to my tv and charge at 25 or more amps? thats three times as fast as my generator.
What about long jumper cables, I have seen a lot of people do this but I thought it was slower than the generator.

J,
I assume that you plug your TM 110 volt plug into your generator when you want to charge your batteries. When you do this your charging rate is controlled by the charger in your TM - just as it is when you plug into a 110 volt plug at a campground. My TM charger is not a very high capacity unit and does not charge at high amperage. It works just fine for people who want to plug in overnight or days on end at a campsite since they have plenty of time to bring the batteries to full charge.
I don't think you would gain much charging capacity with the factory TM charger by increasing the wire size in the TM charging circuit since the charger capacity is itself not very large. This is why they did not bother to put larger wire size in the charging circuit.
So - this is why I decided to go with a separate very large wire size for the charging circuit from my TV to the TM. As I noted, you need a very large wire to get decent charging from the TV because there is only a small voltage difference between the TV battery and the TM batteries to drive the current into the TM batteries. You cannot afford hardly any voltage drop in the circuit or your current will drop considerably.
Since you now have a generator, you could go and buy yourself a good high output 110 charger and connect it to your TM batteries when running it off your generator. But, my gosh, you will have yet another piece of gear to drag about and store - not to mention the noise of a generator.
