For a large pickup you'll want a symmetrical lift, not one with asymmetric arms.
We use 10K Rotary lifts at work all day long to lift cab & chassis F-450s with utility beds filled with several tons of parts and tools. It'll lift a DRW '350 just fine, and you can manage everything down to a focus sedan onto one usually, if you're careful on your post spacing and positioning the vehicle on the lift.
If you primarily work on sports cars and hot rods, asymmetric lifts wth the posts canted inward toward centerline are the way to go. This positions the posts ahead of the doors due to the shorter (asymmetric) front arms and their pigeon-toed orientation.
If you're building offroad rigs or lifting LWB trucks like myself, a symmetric with the posts square to each other makes a lot more sense. There's only one downside: many trucks will likely require you to go on a diet to exit the doors with the vehicle correctly positioned to lift. They hit the posts quick. Some of my, er, less-fit beer bellies coworkers occasionally ask me to pull a truck in the last two feet and rack it.
If you want the model of the rotary and the spacing from pole to pole that we use at work, I can probably round that up for you if you remind me via PM. It's the setup I intend to replicate in my own shop someday.
