No inverter in Travato or the new Pleasureway Lexor. The TV and the stereo/dvd system are all native 12 volt. I'm see that in all the new rv's lately - 12 volt tv sets! A great idea since an LED LCD TV set uses all of 50 watts.
I did buy a 500watt pure sine inverter just to carry along in case I were to need one. I'm probably going to mount it under the driver's seat and hard wire it to the chassis battery. I figure it would be OK to run a laptop on or a phone charger. Nothing serious.
I think running the refer off an inverter is kinda a nutty idea. It's not going to really run any better on 110 than on propane (considering it's an absorption fridge). It will run a loooong time on the propane and your only competitor for it's use is the cooktop. So unless you are running heat, you have months of cooking and refer use with the onboard tank.
