They do not work with multiple battery types at the same time (starting and deep cycle in the same network) since the programs are different and different regulators (with the proper charging program) are required to avoid destroying one or the other.
Okey dokey. I shut up now. I don't see an acceptable solution for this fellow then without, a big battery bank although I like the idea of the inverter in the TV and a 110 volt line to the TT.

Bob, it is kinda "lose; lose" with a 120 VAC only fridge.

Barry's comment is also valid. Short legs to the campground (no more than 5 hours) or a pair (or more) high capacity batteries and an inverter seems to me to be the only options he has.

The inverter in the TV should also work as the amperage would be fairly low; thus voltage loss would also be low.

So bypass the batteries on the TT. Run a large power wire for the TV battery to the inverter. Would that be possible with a HIGH OUTPUT ALTERNATOR 250AMP.

Sounds like an expensive experiment in my opinion.
You, of course, are free to do as you will.
I would advise against it.

I still think the best bang for the buck would be a pair of matched 200 AH batteries and shorter legs if needed.

Good luck.

Still, Wouldn't an inverter in the engine compartment, with short 12 volt leads, and a 110volt wire back to the camper with a plug and a switch be the cheapest solution, given that OP already has the inverter? The OEM alternator should be able to keep up with that much drain, I would think. No connection to the TT battery at all. Maybe need a higher output alternator

Maybe I am missing something...

I'm not sure both sound like they would work. The 250amp alternator in only 300.00 me and my family not have to walk priceless. But most of my trip are only a couple of hours. About 1 or 2 trips a year will be 15 hours one way. Either Destin Fl or Colorado Springs most of the time. My normal on the long trips is halfway and camp. My backside has had enough at 8 hours.
I would like to say thanks for all the comments.
