So your telling us that a frig in a slide is vented different than one in a fixed position...how and why can that be if they are the same frig??

It is not that the refer is built different it is the rig. Through the roof venting in non-slide, the hot air goes close to straight up to get out.
On a slide install the hot air must make a 90 degree bend to get out the slide's side wall.
