I'm looking at the 2011 "RV and Trailer Towing Guide". I assume this is the same through 2014 at least.
Here is the fifth wheel 6.7L data for F550 4x4:
diff GCWR. max tow
4.30 35000 25500
4.88 26000 16300 (1)
4.88 35000 25300 (2)
The (notes) are mine, referenced below.
Help me make sense of this!
(1) How can there even BE an F550 with only 26k GCWR/16300 tow capacity? The order guide says you can order the F550 with either 18k or 19,5k GVWR, with the RAWR then at 13,660 or 14,706 respectively. So how can you order an F550 in the (1) configuration? The Guide does say that option (1) is without the High Capacity Trailer Tow Package. Really? That package adds 9k of tow capacity? I find it hard to believe.
(2) This is the spec w/ the tow package. (The 4.30 entry is also w/ tow package.) This one has me scratching my head also. Wouldn't 4.88 gears give you more GCWR vs 4.30? Here it's identical, and the "tow limit" is actually less.
Confused, thanks for any insights.
