Excess air flow to 1/2 bath
Our 34E has a half bath, the heat vent blows right on the toilet lid. The 2" vent is too much for the size of the room and it gets too hot. I found the outlet at the furnace and taped 1/2 of the hose off using silver duct tape because the outlet is right at the heated cambers. While I had the grille off the furnace I added some screen to the grille to lessen the amount of dog hair that is getting into the furnace. I used duct tape to hold the screen in place and will change it out every couple of trips. We travel with 2 Golden that seem to think it's a good idea to lay in front of the grille.
A couple of simple fixes if you have that problem.
