By "Wing thing" I assume you mean the Wingman UHF director array, What it does is double the strengh of a UHF signal IF YOU ARE POINTING TO THE TRANSMITTER (the Wingman points toward the target).
Get an app or your smart phone, Antenna helper (Free) let it find your location and then choose the MAP option Now you know where to point.
Raise the antenna, Make sure it is turned on (Instructions follow) and point it in the direction indicated on your Smart Phone, (NOTE arrow on dial is 90 degrees clockwise of the antenna's direction)
On the TV, do a Channel scan
Pick a station and then turn the antenna a bit either way to peak
Do another channel scan
Option 2: NO smart phone
do Four scans, start with the antenna rotated fully conter clockwise, scan, and note number of stations see, turn 1/4 turn and re-scan, and re-note, another quarter then finish the rotation pick the best direction return to it, re-scan and then pick a station and peak as above.
Thankfully TV transmitters tend to cluster.
Turning ON the antenna....
Your RV has one of 3 or 4 ways to do that...
1: Most common is a wall plate, there is a switch a light, a 12 volt outlet and an antenna connection,, MAKE SURE LIGHT IS ON
2: Also common: A box of many buttons, these are grouped MAIN TV, TV2, VCR (or DVR) and such,, In each group is ANT, DVD, VCR(Or DVR)(Save that button is not in it's own group) CABLE, and SAT. Choose ANT make sure the power button (Far left) is on (light is on).
Sensar Pro. Touch any button, if the digital displays light up it's on, if not touch top button to turn it on.
Independent switch,, (Very rare) May say WINEGARD on the switch plate, make sure it is on.
I do rather well with the Wingman and Sensar Pro
NOTE: If you have the Sensar Pro there are additional instrctions and some other differences, the method above will work but you can do better, Reply and I'll cover it as well.
