Kimbo Posted July 16, 2011 Share Posted July 16, 2011 Wanted to put A/C in my 83 21ft. Sunrader but the roof was way too weak. Later models bolted metal braces in place but I didn't like the stove bolt method. Ended up using 1.5x3/4 rectangular tube doubled up (to make a 3x3/4) .120 wall thickness. One was positioned in front of roof vent hole and the other aft. Fiberglassed them in place at each end. Quote Link to comment Share on other sites More sharing options...
Kimbo Posted July 18, 2011 Author Share Posted July 18, 2011 After the bracing the ceiling got recovered with 5.3mm sheeting and then a layer of FRP paneling. Quote Link to comment Share on other sites More sharing options...
