You’d expect that. If you reduce air flow across evaporator enough it will get so cold that it will freeze.
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.
