loss of power towing

I use to pull my 5500lb 5th wheel trailer with no problem at 70mph seems the past year it is getting slower up hills. replaced fuel inlet "o-rings" at rear of head, any way to check the injectors ?

I would check fuel pressure.

That's pretty scary pulling it at 70mph. Hope tires are up to speed rating
