Not sure this qualifies as an improvement but this was my first weekend out in our new 2955 and I did something I've done on all my camping vehicles. I purchased some plastic screen material from the local hardware and took all my heat vents off and then cut the screen material to fit the hole and then re-installed the vents. This prevents items from falling into the heat ducts and if something falls into the vent you can usually retreive it without taking the vent grate off.
In this case it also allowed me to do a little final cleaning, it appeared as though the Montana assembly team thought these holes in the floor were a grand place to sweep the excess materials. I found everything from wire scraps to wood pieces and three extra screws that over the long haul I can probably use.
Like I said, probably not a revolution or even deserving of a spot here, but it's always worked for me.
