Kevin, yes, you have spotted the beast. It is omni-directional, meaning (you guessed it) it only does most of them in a semi-reasonable manner. On your roof you will have the plumbing and fridge vents (small, 4-5"), the main vent (crank up, 12" x 12"), the air conditioner (24" x 36") and your TV antenna.
By the way, welcome to the forum and let me complement you and yours on a good purchase. This is a lot of RV for a relatively small amount of money.
Have a big, big time this summer. Relax, take a chill pill (adult cold beverage works great!) and work through the little problems that come up.
