Looks like I didn't finish a thought (wife says I do that a lot). I Tow with mine, 7500 lb trailer, and not uncommon to have equipment in the 20,000 lb range, so 27,500 lb and Im not sure what the truck weighs.
If your use to the pickup Allison, these are a lot different.
nevrenufhp, I finally got my 8.3 running good. Boost hose was worn through and the racor fuel filter was letting air in around the pump. Then I took the top off the p7100, its good now.
