I am terribly sorry but I am just a smidge above being completely computer illiterate, posting a picture is well above my knowledge level. However, I have seen excellent interiour pictures of Boler
and other 'Egg' trailers that often show a wrought iron support that runs from the left hand side of the counter top up to the overhead cupboards. I would understand that a lot of people remove it for reason of practicality - it gets in the way. The support is quite important in maintaining the shape of the trailer, without it the roof sags. When I removed all supports and closet from the Surfside
during rebuild the roof sagged over 1.5 inches, and a particular spot in the rear over the table happily sagged further. When the kitchen and closet were reinstalled the sag disappeared.
I assume you are talking about the roof sagging, not the body sagging?
Mine also had a wicked body sag where the sidewall had sheared away from the floor. I haven't a clue what caused it. I jacked up the body to where it should have been and then proceeded to fiberglass (5 layers polester) the joint so the body would hold in place.
