I've been out in my 3055 cleaning and loading the coach since receiving it last Friday and I turned the heat on since it was cool. I noticed that the furnace ran it seemed like forever and didn't produce much heat at the registers. I counted I believe 5 registers and only two were blowing enough air to blow out a match!!! Those being the one in the commode room and the bedroom. The three in the kitchen and living room were useless. Anyone else having this problem.....
