Norcold 1210 cooling during Travel

Thanks for the suggestion. I actually devised an air scoop on the bottom exterior vent to help with the air flow. I tested it with a leaf blower and it really scooped a lot of air and forced it right out of the top vent. So I thought this was the ticket. Made NO difference at all. I'm starting to think that the coolinf fins are not sealed well enough where they come into the interior of the box. Therefore, while driving the wind turbulence outside is forcing the air through to the box??? Who knows. Now I'm planning to add some sealant around the interior cut-out where the fins enter the box to see if that helps. Phillip
