Thought I'd post the cause and effect of blocking the front of the Vannie. Slowly started blocking off in September with the upper grill opening 'til completely closed off with no noticeable effects on cooling. Did the lower with Velcro attached chloroplast. Everything is now closed including the bumper slits. The ONLY time cooling becomes iffy is when the outside temperature approaches 20C. Then I just pull of the center lower block and everything is good.
Talk about over capacity of a cooling system. It's all good for 2 to 3 mpg, faster warm ups and, most interestingly, slower cool-down when off leading to more residual heat when starting back up.
No noticeable effects from antlers and nose except for plenty of smiles and waves.
Merry Christmas everyone.
