The only vehicles with 'boat-tails' which exist in the United States are reported to the most desirable to tow.
There are no boat-tails which can be purchased and installed on the existing RV fleet, trailer, or motorhome. Personally speaking for myself, I am not limited for solutions that only can be "purchased".
Without 'boat-tails' on the road, I'm struggling with the notion of a 'big issue.'
I suspect this is a case where one must have driven previously a vehicle in strong cross winds that is already sensitive to cross winds and also yearns for a useful solution to reduce drag

* in #9 (permalink ) we find out for the first time that you're concerned with 'typical RV two axle, large relatively rear overhang.'
After 'asking' we still do not know if we're to consider RV travel trailers, or RV Motorhomes/Coaches. Not sure it matters. Regardless, the concern effects I believe, mostly anything two axle, with large rear overhang, that has any significant sidewalls that cross winds would affect, and that a boattail extension would add additional surface area to help enhance that negative effect.

If you had a particular RV make and model of interest, that we could all look at collectively, we might be able to move the dial. I don't, it was a hypothetical question, to repeat myself

I guess my assumption of the threads title was fairly description was overly optimistic.
