The main problem you will find is that if your 365Gl is like mine was most of the through-hulls are too close together. I replaced the holding tank outlet with TruDesign because that was stiff and getting stiffer. That was a great decision. The hull needed to be made a little thicker to conform to the requirements but the other through-hulls and sea-cocks in the heads had to be replaced with DZR items because of their proximity – I got them from ASAP-Supplies to be certain of quality. For the two galley outlets (well actually one is an inlet) I did use TruDesign.
Had there been room I would not have hesitated to use TruDesign throughout.
