Sonny, you could try searching "Ventura center seam repair" using the google box in the Search pull down link at the top of the page.
Many of us have repaired the center seam on a Trillium
, and various techniques have been captured on numerous threads for that repair. However, I suspect the Ventura
center seam construction is different than the Trillium
, the Boler
, and many other FGRVs.
center seam has no wood, except that the Trillium 4500 center seam has a wood backing along the rear side. Other than this, the center seam is held together by a 4 inch wide strip of fiberglass applied around the inside of the trailer. To complicate matters, 40 or so small steel plates (about 1"x2" each) are sandwiched between the center seam and the 4 inch wide strip of fiberglass. The small steel plates rust out and then the aluminum trim that is riveted to the small steel plates pops out. Most owners grind out the steel plates, grind off the gel coat layers, taper the center seam edges and apply a fiberglass strip around the outside of the center seam.
Apparently the Ventura
does not have a fiberglass strip applied on either the inside or the outside of the center seam, but instead, just wood inside and trim outside. Is this correct? If so, expansion and contraction may lead to leaks
again if you use butyl tape. You may need a stronger bond, i.e., 3M 5200 adhesive or a fiberglass strip applied after grinding off the gel coat and tapering the center seam.
