I bought my 40 with a vintage air unit already installed. I think I found out why the heat didn't work so well. It appears it was never hooked up. At first I just thought it was because the hose is kinked, but then I realized the hose just connects the bottom pipe to the top pipe. It doesn't connect to the Vintage air unit at all. Can someone tell me if I'm just not seeing things right.
And please post some pictures of your connections including how you kept the rear heat, if you did. I have pulled the whole unit out to rework the vehicle wiring. But when I put it all back together, I want to add a rear heater.
