Experience needed: New RV delam bubble on rear wall

If it is delam on a new rig the only true fix is having it returned to the factory for wall replacement. Anything else is a band aid fix and I for one would not accept it on a new rig.

No need for this trailer to go back to Coachmen, any authorized dealer can replace the wall, just as the pics I've posted illustrate. To answer the OP, correct repair is replacement of the entire wall as a unit ... sounds like a big deal but really isn't for a qualified tech.
