swapping 3 way fridges

something happened to my original post. I thought I typed that the 1999 fridge is a 3 way, but manual, and the 2005 fridge is a auto switch. I am not sure about the pilot light situation. I know the 1999 is a manual light with a push button at the top of the fridge, and there is no button. However, in the year and a half I had the popup, never used it on gas, only electric and 12v while driving.

Just seeing everyone who wants to, 2 cent's worth on switching, or if it is more trouble than it's worth
