Well, as I pointed out ... there's much more to the story. In my motorhome, I took out the 3 way fridge. I installed a new Norcold 110/12 volt refrigerator. It's a tad smaller, at 7 cu. ft., but 2 door and it draws about 40 watts. It utilizes a VERY well respected Danfoss variable speed compressor cooling system. I installed solar panels that will much more than power that miniscule power drain.

I just put 250 watts of panels on my Avion. I think I will sell the 3 way and install the same super-efficient Norcold in there too.

I installed a Magnum MSH inverter in my new Classic along with four Lifeline 6V batteries. Also 600 Watts of solar. In rewiring the main panel into the sub-panel (inverter circuits), I moved the 120V fridge wiring onto the sub-panel -- which means I can run the Dometic off the inverter rather than use propane. IF I'm traveling on a sunny day, the panels will keep the batteries well above the programmed low battery cutoff point (this is programmed into the inverter and keeps you from over-draining the batteries --- which could cause them to be damaged). I tried this set-up and it does work.....but for all practical purposes, it's a LOT easier to let the Dometic flip over to the propane. Then if we pull over in a rest stop and want to have a sandwich with toast, or use the microwave there's plenty of "juice" in the batteries to use the heavy power consumers.

It is a great question though

Other better options.

Just run the fridge on propane while driving.

If for some reason you can't or won't. You can run the fridge on 110 for a few days before departure ( you really need to do that any way ) Then put frozen bottles of water in the fridge right before you leave, and don't open the fridge until you arrive at destination.

I installed a 10 gage wire from the TV batteries thru a fuse to an outlet on the back bumper, then I have a separate wire from a matching plug thru a 120 volt controlled relay to a 300 watt invertor powering my Dometic model 2452 120 volt refrigerator. This refrigerator uses less then 2 amps to keep it cold. 2 Amps x 120 volts is 240 watts, divide that by 12 equals 20 amps from the TV batteries.
If you have a 100 amp alternator on your TV, you should not have any issues keeping everything cold.
I have a homemade lashup that has been working just fine. Total cost including the wire about $300.00

I have 4 solar panels and a 2800watt inverter. On an average sunny day my solar keeps the batteries at a 100% charge even though the inverter is running the fridge and other items. I guess I did a proper installation. Running down the road with gas on is dangerous.

I use a 300 watt invertor supplying enough power to the 120vac circuit to the refrigerator. The refrigerator keeps ice cream hard enough to stop for a cone traveling through Nevada.
I use separate dedicated 12vdc 10 gage wires from the TV to the invertor not the regular7 prong 12 vdc supplying power to the AS for brakes, lights, and trailer batteries.having propane on while traveling is just asking for problems.

What are people using as a connector between the tow vehicle and the trailer to carry the larger amount of power?

I don't have mine set up as a separate circuit. But if I was I would use the Anderson Powerpole connectors. I have built a couple of extension cables for my portable solar panels using them.

I am using a 4 pronged receptacle and matching outlet using 2 of the connections for supplying 12 vdc to a relay controlled by a 110 vac circuit (not the refrigerator circuit.)
