Injectors
Need help!!!!!!!!!!!! I am in the process of replacing all (8) of my injectors. Problem started when I was hooked up to our camper and pulling up a slight incline I lost power. Going from 60 down to 15 within 1/2 mile. dealer replaced 1 injector and said that I was good to go. Not hooked up again with the same problem. What would cause the injectors to go?

A few things will KILL Injectors
1. Low Fuel Pressure
2. Not changing the Oil at correct interval
3. A bad FICM from Low Voltage
Most of us do the Blue spring mod to keep fuel press alittle higher. The injector is a side Load and Plunger Driven so the fuel is the Lube for the Plunger
To low Fuel Press will cause the plunger to Wear and hang up

No as there isn't a fuel pressure sensor. You NEED to get a fuel pressure gauge for your truck along with an EGT gauge if you pull a lot. I really don't think you're having an injector problem. I think the OP has other issues.
Have you cleaned the EGR and possibly the turbo?
