Hello
I have a 1980 LeMirage that began life as a motor home and in updating the house systems I am considering adding a skylight in the shower.
I currently have the refrigerator out which is on the other side of the wall from the shower; changing it over from absorption to a DC compressor and I can see what looks like a heavy duty attachment point that should be anchored in one of the ribs.
I know my bus has an outer skin, rib cage/foam insulation and inter skin sandwich. Question, how do you go about locating the ribs?
