Slide or pivot?
What does the tail look like? Any plasma actuators?

The carbon fiber rear tractor skirts are
both hinged and have horizontal sliders as well. The hinges are on top end of the skirts. We have race car panel buttons on the outside of the skirts that we simply push to unlock the panels from their skirt hangers. We then slide the whole skirt outward 4" on the sliders until they meet fixed stops, then lift the skirt up over the hangers. We needed the 4" of travel on the sliders so the skirt would clear the trailer when it was connected to the tractor. Without the sliders, we would not be able to open the skirts past the 90 degree opening point.
The mechanical tractor to trailer gap sealer on the rear bulkhead of the cab is very similar to the boat-tail below. But it has one continuous top panel in 3 sections, as opposed to the 2 separate panels on the trailer, as there are no doors on the rear of the cab.
I have an amazingly cool video of the gap sealer working in Augmented Reality (AR) that I cannot share yet, unfortunately. When we tweak the AR some more for accuracy, I'll be hopefully able to post it here.
We have been talking with the plasma folks for a couple of years now, but it's not ready for prime time yet.
The trailer boat-tail is an active aerodynamic, 4 panel WABCO unit that they custom built for us.
It is stock except we had them extend the side panels downward to the top edge of the horizontal impact protection bar (bumper) at the rear of the trailer. So we basically have a laminar flow that is not interrupted from the rear trailer skirts to the boat-tail, unlike almost everyone else. They are pneumatically operated and currently open at 40 mph and stow at 10 mph, keyed off of the WABCO stability control and ABS computer on the trailer. We may tweak those mph settings.
As you can see from the images below, Strick built this trailer for me without any light cut-outs in the rear stainless steel door frame. We have 24" wide, 1" tall DOT approved LED taillights, mounted
inside of that rear impact protection bar. When the boat-tail is stowed or deployed, a vehicle behind the trailer can still see the taillights and that conspicuity tape.
The top panels are in the stowed position while we install the full-length side panels.
