I pull the same grade 3 or 4 times a year in my 04 f-150 with the 5.4 and 3.73 gears.My rpm' s are around 3800 at sixty mph.The truck loves pulling in this range, and sounds good doing it.I have passed many diesel trucks pulling this and the saluda grade. I wave as I go by.And smile a little.
You're not towing very much, I also run that grade quite often while towing sig 5er @ 16,000# and can also maintain 62mph easily...same with I26 from TN into NC, (7%), I64 in WV from Sandstone Falls to Beckley,(7%) only run 62 or so going up, speed limit is 70, I don't WANT to do 70 and there are 3 lanes in both directions...also Black Mountain, easily do 60 mph...
I had a 1999 Chevy 1/2 ton with 5.3 and tow package and was stupid when I went from a 27' TT to a 27' 5th wheel and came back from Myrtle Beach up the Saluda Grade, was in 3rd lane and wondering if I was going to maintain 30 mph to the top of the mountain, KNEW I was hurting that particular truck, (was a 99' and overloaded)....got home, and next business day, got an 01' 2500 8.1/A...(couldn't find a D/A at the time, was like trying to find hens teeth at the time:))
The OP's RPM sounds about right, I would prefer to use a TT or 5er's ACTUAL GVW and not a dry or empty weight, it can really fool you if you don't use the one that makes more sense.....and it's NOT the "empty" or "dry" weight..
