Yeah, we have a variety of space heaters that we can try. I like the idea of the park payin for my heat. Like I said in the other post, Winnebago tech support told me the duct work was encased in Styrofoam and therefore inaccessible. Next trip, we'll play with closing off vents just to see if we can get the air flow up front.
I have verified that the ducts are connected and free of obstruction to the front by blowing air from the hall vent towards the front. It appears that the design may have issues but like everyone else does, we can carry auxiliary heat. At least the floor system will do that which matters most to me by keeping plumbing pipes from freezing up. Already put the drop light in the water compartment as suggested by Winnie tech support.
