I suspect your Tropi-Cal door is the same as our 03 Tradewinds. The entire striker in the door frame has to be removed in order to adjust the in/out position. Remove (unscrew) the striker pin in the door jamb, then from inside the coach, remove the black plastic cover and then the screws holding the striker in place. Once removed, the position of pin can be adjusted. Somewhat hard to discribe, but will become evident once removed. The adjustment is somewhat trial and error. With the striker removed from the door frame, I would mark the current position before making any change so you have a reference point. Hope this helps.
