Now that I have had my 2013 301 for over a year now, I have definitely noticed that there is a huge difference in the temperature of the coach and the garage when camping below 50 degrees. The little 1 1/2 inch heater vent does nothing back there. It actually blows cold air. Since air comes out, I know there are no obstructions, just a lack of engineering to run a small hose that much of a distance. Normally I would just tell the fellow campers that I stick in the garage to double their blankets but I have toddlers sleeping back there. This seems not to just be a Heartland issue either. People say they designed it to be a garage, yah whatever, there are two queen beds back there! To try to get it warmer back there, I made a couple of modifications.
I am camping at the beach next week. I will update you with the results!
- I lined the bottom of the garage with 1/2 inch rigid foam insulation boards. in some places, I liquid nailed them right to the plywood
- I put in a piece of carpet with carpet padding that I can roll up
- I found a huge empty void on the side corner of the ramp door n the steel beam. I filled this void with 2 inch insulation foam and spray foam.
- I also flipped the direction of the sliding glass door. Now there is a full size vent shooting into the garage
