With a lot of Ford chassis’ the marker lights are on the same circuit as the trailer lights.
This so that, in the case of a dually for instance where you can’t always see the trailer behind the wider fenders, you see that your fender markers are out and know your trailer is out too.
If your unit is on a Ford commercial chassis check the trailer fuses.
The WUF is a pusher and there may even be a switch for the DOT lights on the dash. They are often used to signal a passing big rig or other vehicle it is safe to return to the right lane.
Go to Winnebagoind.com/resources and find the electrical schematics for the UF. It may be in the owners manual also found on line as mentioned above.
