Neat picture, but how does it compare to a non-boat tailed semi?

I don't think we currently have one with the exact same truck without a boat-tail, because we knew from day one we wanted a boat-tail.

I've wondered if it were possible to have an inflatable boat tail that would provide aero efficiency on the road, but deflate when pulling up to the loading dock. Neat model.

That looks nice.
I only have one complaint: All the cool projects I'd like to see/help out with are across the country
Orbywan in AZ, you clear over in the other corner of the country, Phil in Texas.

We should be in your neck of the woods sometime this year.

We have two Sponsor's/Business Partner's up the street from you in Seattle. And we'll prolly head through Tacoma going up or down I-5.

I can shoot you a PM when we get close to that trip, and give you an in-person nickle tour of the rig.

I'm about 2 hours away from Newington. Have any free time on a weekend for a Freightliner tech?
