I can't speak to the trailer.... but it is a fairly large trailer for a v6 SUV.

Exactly. We're walking about
with a trailer. That engine might be perfect for the SUV alone, but adding 2000lbs and terrible aero is too much for said engine, imo.
Here's a 6.2l silverado with a
7000lb trailer, of similar shape, getting 10.9mpg:
All I am saying is that 3.6l has to work a heck of a lot harder than a V8 would. And when you use an engine near it's (torque) limits, it pushes it out of the efficient area of it's bsfc.
True enough that with VVT and direct injection, they
might, theoretically, be just as efficient at full torque, but historically gasoline engines always run richer at full engine torque than they do at, say, 80% torque.
