There is no way I wanted to wheel a Titan, hence the 2wd...as far as towing goes, you wouldn't have a problem pulling both (the trailer with the X behind it) I barely know I have something behind me pulling 5K+ #'s--The X pulled the same trailer without *too many problems (didn't like hills much).

Problems with wheeling a Titan:

expensive vehicle, poor approach and departure angles, thin sheet metal (it dents if you breath wrong near the truck), lack of *functional* off-road equipment for Sierra type terrain (though some lifts are fine for Baja type running), too wide/long of a vehicle, depending on configuration good luck getting suitable tires, etc...

It's a great pickup, just not what I would consider purchasing for offroad use beyond dirt roads and gravel travelling to improved camp locations.
