The point that was being made, I believe, is that for most owners who complain about the RV being too hot, it shouldn’t make much difference. When you have air going in at 80F and coming out at 60F because the A/C is already cooling at maximum 15,000 BTU/hr, how is moving the prove going to help? When it’s really hot inside RV, everything is already designed to call for maximum cooling capacity.
Well you don't even own an RV so I guess you don't have to worry about how efficient these roof AC's are.

Seriously, this all goes back to a basic question... Do you (the rest of you guys too) think manufacturers like Coleman, Thor or even Ford create products that are at 100% efficiency in 100% of the end users situations?

The factual answer to that question is no, they absolutely don't. There are few products made in this world that can't be improved upon in at least some tiny little way. It's actually what drives innovation, end users not being content with the operation of some product, and taking it upon themselves to modify it to work better. Many times those "mods" get evolved into actual production changes. And the world becomes a better place. lol.

If I trusted Ford to deliver my V10 engine with the best, most efficient engine calibrations, my RV would be down about 80 ft/lbs of torque right now. If I trusted that Thor made the most efficient RV, I'd be camping in a vastly inferior coach than I now am. And if I trusted Coleman to make the most efficient roof AC unit for RV's, I'd be a helluva lot sweatier while in my RV.

The simple fact is that these roof air conditioners are NOT running at their peak efficiency in any particular coach. The design has been basically unchanged for decades, and a few different models are supposed to "fit" all the different RV designs and configurations on the road. There absolutely IS room for improvement on operation of this particular product.

If you want to be a Negative Nelly, that's fine. Just don't keep squashing the hopes and dreams of the rest of us that like to mod things and enjoy the improvements and newfound knowledge that it brings.
