1. WHY he would pull the wheel assblys apart shows complete lack of knowledge. The fact you had BOTH running lights and brakes issues points to one thing---The 7 way connection at your Truck.
2. I would not think the 4x4 junction box on the Jayco trailer(where all the tow plug wires go to) would be an issue as I would hope the Tech checked that
3. The usual cause of your type problem is a rusted trailer 7 way end or your truck 7 way has a problem.
4. An easy check is to connect your trailer to a friends truck and test drive. If the problem goes away your truck is the problem. If it stays then check the Trailer 7 way and the wiring to that 4x4 junction box which will be where the A frame is welded to the front trailer on the outside. Doug
