To keep refrigerator running

I personally don't see a need, but whatever floats your boat.

Another item of concern for me would be the very large choice for the POWER INVERTER. A 2000 watt unit will want to draw around 160-170 DC AMPS CURRENT (or more) if fully loaded down and this will do a big number on your truck start battery system. Just using a single battery 100AH or so will only give you around 15-minutes of use before running down the battery. This may also do damage to the truck start system alternator... This is alot of DC Current being used probably demanding more current then the standard truck alternator is producing...

Just my thoughts here...

And it's not "scary" to have a sheared 120 vac cable flinging about? :h

According to the RVIA there are currently ~ 8.9 million recreational vehicle households in the US alone, the vast majority of those being travel trailers and fifth wheels which would normally be equipped with a 2-way gas absorption fridge. While there's always an exception to everything the reality is the vast majority of these owners tow with the fridge running in the gas mode. With only a few exceptions for traveling through tunnels, over bridges, etc, there are no laws in any state or Canadian province or territory that forbids towing in this manner. Think about it - if both government and the recreational vehicle industry saw your solution as THE solution as well we'd all be doing it by now. How you tow is up to you but the vast majority of us run our 2-way fridges on gas whenever 120 vac shore power isn't readily available.

So.....first be sure that your fridge isn't this kind. If it IS, your problem is mostly gone.

I have always traveled with the tanks closed off.

Some perspective: The LP lines in your RV run at about 0.5 psi. The fuel lines for your vehicle's engine run at 40+ psi. Both have safety shut off mechanisms.

To keep my fridge working, I installed a second battery with a smart isolator in my 2011 Silverado 1500. To this battery I installed a 2000 watt pure-wave inverter and a 110v weather proof outlet. I connected the shore power cable of the TC to this outlet, wala I had all powered except for AC.

Now can I do this to my small (Shadow Cruiser 195wbs) TT.

What are your thoughts on my idea.

I think having a 120V AC connection between truck and trailer scary. Actually, there is little chance of a mishap but I keep thinking of a short to the truck body and someone unbeknownst getting a jolt when completing the path to ground.
