Pix or, you know....[/QUOTE]
SMART TRUCK AERO DOT COM
See: Topkit
We are using with skirts.
I like to think fully boxed tail is best, but even with our experienced men, they run into maintenance issues (an owner-operator could stay ahead of that). I also like it as I think it keeps tailgaters farther back (and I like the look when paint scheme is excellent: a clipper with all sails out).
So far as I can tell the crosswind problems are low (given fresh fifth wheel grease and balancing load by sliding tandems). I’m under a 44k load in the box (gross 78k) from Amarillo to near Clemson, SC and have had crosswinds though not fierce, are noticeable.
A load that with a non-aero trailer I’d be in the low sevens at my usual 66-67 mph. Instead, I’m at 7.8-8.3. This series of trailers are new to us. All disc brake and our norm of auto tire inflation. Conventional tires (wide base singles not really working out for fleets).
Top edge Nose splitter. Turning vanes at trailer sides rear top. Full width turn vane on roof. Full skirts. (Which I much prefer to undertray type).
I Expect tails to disappear. They’ve had their day
2019 Peterbilt 579 EPIQ package. 12-Auto. Full FLOW BELOW” package on Drive Axles. I’m at a little more than 30” gap truck to trailer keeping kingpin centered between axles. Might try it forward more, but ride quality is something I can’t screw around.
At 64-mph with barest tailwind I can travel in this 21,500-lb tractor bobtail at near 14-mpg. 11-12 otherwise. 10, almost always. That’s as good as some of these diesel pickups solo and towing. 6k lighter and one-half the engine-size, ha!
I first came across Coanda in a series of articles in ANALOG in the early 1980s
NUSSBAUM fleet has been a model for our owner (but thank god, we’re not in Freightliners. I’m in a Cadillac, not a Cornbinder quality ride).

Congratulations! With my bonus ($0) I ended up in Rockport, TX. Bring your Aloha shirts; we have the cocktails.

The highlight of my day yesterday was hurriedly carrying my cylinder head into the garage, tripping on an extension cord that I had tried to put away, catching my balance, and setting it down safely.
I put away the extension cord after work when I tried to mow the lawn.
How many places can a lawnmower hide?

The snow is melting so suddenly it sounds like an episode of Dukes Of Hazzard in the "neighborhood" again. Oh, and the breeze must be from a direction that dictates all air traf f*** go directly over the "neighborhood" a.k.a. "residential area". On the bright side, about 17,000 cigarette butts are now exposed out in my yard by the curb.

My mornings are nice, especially when it's cold and nasty out. Up at 5, get the dog out, then maybe 20 minutes or so in the basement hot tub. Then a nice quick breakfast before getting the kids up and beginning 14 or 15 hours of mayhem.
If the day's mayhem isn't too bad and I've got some time and energy left at the end of the day I can go back down there for a while before bedtime. I always sleep better after that.

And wake up cleaner too.
I used to live like that (in a geodesic dome). The alarm went off at 4:20 and I'd spend a half hour waking up in the hot tub. Then in my chair for the six o'clock shift.
Good times.

Since the hurricane blew away the trees, good luck. Like Galveston, no reason to go back again.

Hey, we're looking good down here. All cleaned up and in business since last year. Yes, we lost some trees, but the beach is still here.

No. Not the same. Won’t be in our lifetime.
