Our latest trailers have a vestigial lip. Splitter.

I’d sure like to try the above full form.

BUT trailers take damage. Surprising amount at front. Usually as it’s getting jockeyed around by a yard dog at a shipper.

The trailer pictured is a high dollar unit. That stainless plate ain’t cheap and it’s heavy. Plus, there’s little call for a man door (again, expense & weight). What we see is a covered wagon with sliding cover. A flatbed with a permanent “headboard kit”. Mated to a high-profile aero tractor. That cover reduces aero drag by over 9.8% according to the print on the back of one I was following the other day.

Flatbeds can generally use a flat-top tractor (the type where you lay in bed to git them Wranglers on). Low light tractor and light trailer mean good economy with a huge payload (50-52K in some instance. I max out at 45.2k with a van and midroof).

The pic is also what we’d very likely see with a one-of-a-kind trailer mated to a custom tractor. The sort of units I see with mobile broadcast facilities, etc. A trailer that, with gear aboard, is worth millions.

“Aero” is, let’s make the insurer happy (reduction of driver workload).

Sure did do a lot of work, and it looks great.

Is that a little hydraulic fluid on his drive from the lifting/spin mechanism?

Always more work to do.

The book sounds interesting, but I don't see a price. Maybe I'll recommend it to the city library.

I see the thread is lacking some Space Junkie:


Just A Car Guy: Ian Roussel's Space Junkie 2

edit:
Nothing new here, just possibly the first attempt at a flying car. The 1929 Guggenheim Competition was to find an airplane as easy to pilot as driving an automobile.

Thanks, I've never seen gravel shields before.

Looks like some are stainless steel and hinged on ones side so you can clean behind them, others are fixed in place.

All designed I assume to protect the thin aluminum skin.

From the original image, they mistakenly looked like bulbous bow deflectors of some unknown type - mystery solved.
