* I'm of a similar opinion.
* While the semitrailer, involved in 'commerce', must justify some rational economic justification for it's inclusion, compared to 'conventional' dry vans, the RV 'teardrop' trailer ( the entire RV industry ) remains a 'want to have' luxury, hoping to attract dollars away from competing products, with the nebulous promise of some vague, perceived advantage, over other products in same price range, while offering no actionable contrasting information which might actually 'inform' a potential customer about 'real' attributes.

While the trucking industry participated in, and contributed to, the 1980's semitrailer aerodynamic technology developed alongside NASA's R&D at Edwards AFB, California; it appears that, until the advent of electric mobility, nobody in the RV industry, with the exception of two new startups, are even aware of what was 'discovered' by 1980.
There are no 'teardrop' trailers in existence, within the 'aerodynamic' context of 'teardrop,' as conceived within aerodynamic parlance.
No one except AeroStealth, in his YouTube videos, has shared anything in the public domain, remotely approaching the actual fluid mechanics of RV trailers of any stripe.
