I installed a MaxxFan on my EggCamper
. Also installed a WindowMaxx on the starboard side window. It gives great ventilation and allows me to keep the window open in the rain (not that we have been getting much rain here this summer!). The low profile of the MaxxFan when it is closed was a big selling point with me. It fits the style of the camper. And it doesn't require an additional rain cover.
BTW - I checked all the local RV parts outlets before buying the MaxxFan and found price differences of over $60. I asked the supplier with the lowest price if they would be going on sale soon and he told me they would in the fall
. About 5 minutes later he walked up and said he would sell me one for the upcoming sale price. Saved another $25.
Anyway, I highly recommend the MaxxFan and the WindowMaxx.
