We own a 2016 28RKX MAXX. I have 1 more suggestion for a "mod" you may want to do. In our trailer, you can feel a lot to air movement, especially in cold weather, coming from the front cap area into the trailer through the open area below the hang up closets on both side of the bed. We asked about this and was told it's to "ventilate the front cap" ( who knows???). We did however, have mouse droppings in one of these openings and on that corner of our bed spread after a long storage period. Based on that situation, we decided to close these 2"X10" (approx) openings to the degree that small animals cannot enter the trailer. I bought some very light metal cross hatched material with openings too small for the critters to get through, cut it to size, put some black duct tape around the edges, and screwed it into the paneling inside the opening. We have had no critters since the mod and still allow the cap to be vented. If I say so myself, it looks pretty nice too if you peak into the opening.
Have fun with your great trailer, this is our 2nd MAXX as we had a 28RG for a year before we upsized. Nothing about this trailer we don't like and it's essentially been trouble free for the year we've owned it!!
