I tried to replace a bad outlet in my trailer with conventional outlets. I tried two different types of "shallow old work" boxes from Lowes. There is not enough space between the inside and outside skins to slip the box in. Since the existing outlets take the place of the box, you are pretty much stuck with the RV-style outlets. At least that is my experience.
