Brake light comes on on tow vehicle towing camper ???

After about 30 to 50 miles down the road towing camper, brake light comes on on our 2012 Dodge Durango . I suspect it is because the trailer brakes aren't being engaged well nuf by the brake controlle...

The brake light wont come on because the turck doesn't think the trailer brakes are good enough.
Brake light comes on if there's an issue with low pressure in the system, if there's a computer or a few other obscure reasons.
I would check the brake fluid level first. After that I would make sure nothing is leaking, especially at the wheels.
