I have taken mine through a carwash at least a dozen times (the ones with brushes, not the touch-less), I also have a fiamma awning. May not be the best thing to do but I haven't had any issues so far and in the wintertime in Utah I rather get the salt off and there is no option to wash it myself at home during the winter and its just plain easier. With the fridge vents the way they are I wouldn't imagine much more water gets in there vs driving in the rain etc (I could very well be wrong, just my justification).
