Our class C with a 5.4 leaves our driveway at 10,380 pounds. It's a 2003 and we have lots of mountains we go over. My trans gauge hardly moves on our hottest days going up steep grades at freeway speeds. My gauge barley moves going up steep logging roads at real slow speeds. The cooler is stock, so no need to go for a monster size like 6.0's have.
Also when doing the install I would also put in one of these. http://puredieselpower.com/manufacturer/magnefine-2 and NAPA has their own brand also (same thing just painted different).
There's probably more info with spec's that can be found on-line.
Just because the Ford idiot gauge is not moving doesn't mean the tranny isn't getting hot. Mine tranny gauge doesn't budge until 235 degrees. That's why I have a Scangauge. I want to know if if breaks 200, not 235.
How far off is your gauge, if known?
