It seems to improve slightly if I lock 6 gear out to avoid lugging at low rpm's.

Here's the kicker, and I don't know if it's a real diagnoses or just me being to picky (interpreting minutia bumps in the road), but I feel like the engine is sputtering slightly, almost as if it's lugging at low rpm's...but like I said, I'm locking out 6 so the rpm's are up. It seems to idle very smoothly tho. I pick up the camper Sunday out of storage so we'll see how I do on the 100 mile trip home with it. Dry weight is roughly 8000 lbs.

I might have a mechanic take a listen and see if they are hearing what I'm hearing. The tranny shifts without flaws so far, but I'm just at 1000 miles.
