Making blind side turns at night

I haul waste from produce out here in washington and most of the driving is on these narrow, beat up, ####ty country roads that can barely fit 2 cars on with ditch banks and power poles on every corner of every road. Im using an old ####ty worn out freightliner with ####ty old mirrors and ####ty windows.
When im trying to make right turns on these super narrow roads with no street lights, i can't even see the where my trailer is going, if i cut it too short the trailer will land in a ditch, both lanes on each road could barely fit the truck itself sideways on, im running 53ft side dumps and i have to get right up on these side roads to dump

My question is does anyone have any ideas on how i can make these turns and be able to see where my trailer is going, all i can see if just the little red marker light at the back of the trailer, i cant see the stop sign i just passed, cant see the ditch bank, cant hardly see #### but im doing 12 loads a night and i dont wanna #### up and side swipe a power pole or hit a stop sign or tip the trailer over in a ditch. And as a reminder the trucks got ####ty windows, ####ty mirrows, there are no street lights, no lights anywhere around me to help me see.

 

I cant. Im working for a company, runs 24/7 during harvest and im hauling 16 hours a day from 8am to 12 at night 7 days a week, its a rough messy job but it pays the bills

 

I just tried the flashlight in the mirror and it didnt work
