I just got some clarification on the "round bar" vs. "trunnion bar" type hitches from the manufacturer. Apparently, it is simply a matter of preference. Each style is more popular in different areas for different reasons, but neither has a real functional advantage over the other.

As it turns out, the "trunnion" style provides more ground clearance since you don't have to come out of the bottom of the hitch and turn 90 degrees back on an arc as you do with the "round bar" style. Look at pictures really close and you'll see what I'm talking about.

According to Ford, my truck (2005 Expedition)is only good to 6,000# without a WD hitch and 9,200# with (since I have the HD tow package).

I ordered a 10,000# trailer with trunnion bar style WD hitch today. Trailer sits fine without the funky hitch, but safe is safe. Leonard is installing the hitch with 1,000# arms for $320...pretty cheap to not have any question about carrying capacity.
