I don’t have a 17b, but the RV fridges I have pulled out have always been 3 ways, and easy to do. Remove 12v +/- usually on a terminal block, 120VAC, usually just an outlet, condensate drain that just practically falls off, a gas line with a wrench or two, 2 to 4 bottom mounting screws, and some interior trim and screws. This allows it to slide out into the trailer. You may need to remove a pin or two, or a few screws to remove the fridge door to get it to fit out the trailer door. I know on some gen one Escapes, the trailer door frame had to be removed by taking out several screws.
Starting on page 5 post 84 is where I removed our E19 fridge.
