There are some very minor changes that I have noticed. MBG has always been great about listening to customers and making changes. The under gunnel rod holders on the early trs had 2 holders where the new ones have 3, the battery switches and breakers are in the console instead of the aft hatch, and the t top feet go to the deck in the front and rear vs the front only in earlier models. These are all very minor things. The switch location makes no difference in my opinion but I see why they did it. The extra rod holder is something I will be adding and is a simple fix. The t top brace would be nice to eliminate flexing in rough seas but I do like the extra room while at the helm. There are also latches to lock the rear seats down on newer models but that again is a simple project.
