Our rig is in my signature. We have a Coleman Mach 1300 btu AC unit. The AC unit blows cold air. It has the quick cool down vents when open blow massive amounts of air by design. The issue I have is very little air flow from ceiling ducts to the rear of coach.vs the front of coach ahead of AC unit. I have closed both the quick vents thinking that it would boost ducted air flow.Not so much. I do understand that the duct runs behind the AC units to rear of coach are longer and could factor into diminished air flow. Am I missing something or is it just what it is? We do have fans to help, but can I increase ducted air flow. We will be in the Bad Lands next month and anticipate the use of AC.
