Or, as with the later 1959 Airstream "Overlander":



Also, does The side radius has been reported as a source of sway need to be corrected to the lack of . . .?

Thanks

Yep.They have some advantage at zero-yaw,but from graphs Hucho published in his book(s) they really dominate low drag under crosswind conditions,which is what we have much of the time.
If the gap can be closed as well(which is responsible for almost all crosswind drag) we pick up even more savings.
The 1982 'trailer dome' by Fibrelock Ltd. did both operations and was credited with up to a 26% fuel savings.After working with Hucho's material on trailers and commercial vehicles I believe it.
As to crosswind stability,Fibrelock claimed that their unit actually reduced pitching and snaking.
If the gap is closed off the yawing moment will be killed.You'd feel some 'push' but that's to be expected when you are pushed from the side.
If we watch our load distribution and tongue weights we ought to be okay.
