One switch turns the TV antenna amplifier on and the other turns on the Winegard "Connect 2" wifi booster and 4G LTE antenna on. The Connect 2 is prewired but not installed by Dutchmen, its an aftermarket accessory. Look closely at the TV connection plate, may need a flashlight shined at an angle, the two buttons are labeled; one will say TV, usually on the left, and the other WiFi. I printed labels and stuck them on the plate so they are easier to identify. I also installed the Connect 2 to be able to stream movies and make phone calls over the internet when a weak signal is present, very satisfied with the connect 2. If you decide to install the connect 2 there will be a plate on the roof of your trailer, mine was about a foot way from the Wingard TV antenna. The plate will be sealed and you will want to ask this forum for help in removing the dicor sealant around it; it's not easy and you can easily damage the roof membrane if not done correctly.
Happy trails and enjoy the new trailer. After your visit to Buescher State Park TX post a comment/review on campendium.com if you are not familiar with campendium, great place to find info on parks and boondocking sites.
