One of my only functional complaints with the 23MBH has been that the bathroom does not have heat. When the temps are below 45 degrees the bathroom really never gets warm. Today I decided to change that. I removed the black panels below the entertainment center and found plenty of space for running duct work. So I drilled a hole at the back of the furnace and inside the base of the entertainment center. The hardest part was fishing 4 1/8"" duct through a 4" hole as didn't have a 4 1/4" hole saw in my shop. Took about two hours and I was also able to install the underbelly heat at the same time. I wish Jayco would have offered the option for ducted heat in the floor. There is plenty of space for the ducting.
My next step will be installing a 30 amp plug in shore power adapter so I can free up more cabinet space under the entertainment center.
