Our 2720SD was not 10 minutes old before we removed the wardrobe cabinet. It just was something my wife wanted out of there right away to make room for the three "flip-lid" boxes we place on the counter top by the bed. One clothes box for me, one for her and one box of food. If we have an extended stay, there are two flip-lid boxes for food that we stack on top of each other and we then have the do the "food-box-shuffle". It's just the way we do our camping especially since it is difficult for us to open the TM to load items before departure. So we don't store our food in the trailer cabinets.
Anyway we didn't have a good spot to hang light coats like a rain slicker or even the towels after they dried on the towel rack. Such items were getting in the way.
So I went to the hardware store and purchased a grip bar, something a little more beefy than a towel bar. Another advantage of using a grip bar is that grip bars tend to have more mounting holes to add strength. Towel bars usually have one or two screw mounting holes per side. The grip bar had three per side. I purchased 3/4" stainless steel pan head sheet metal screws in the largest thread size I could find and mounted the bar upside down as in the photo. Now I have a place to nicely store hanger type clothes and towels when I'm not taking a shower.
Works great! One very minor disadvantage is that since the ceiling is sloped a bit, items on the bar tend to slide to the street side wall of the trailer. But that is a minor problem. I am also not tall enough for this bar to cause problems when I use the shower.
I measured a spot on the ceiling to make sure to clear the board to the left of the kitchen sink when the top comes down. In my case I mounted the bar a little too much center of the shower area and the coats tend to get in the way just a bit when using the toilet (for us men)
. If I had to do it all over again, I would move the bar back 2 or 3 more inches to the rear of the trailer.
Basically, whatever is on the ceiling will be 4 feet moved to the center of the trailer when you put the halves down. Keep that in mind.
