Works both ways.. When parked, an insulated curtain keeps all that heat of the greenhouse which is the cockpit.. In the cockpit
When driving it means the dash air can cool the cockpit without needing the generator to cool the house.
As to why to find reasons to not use them (Convinences like generator and roof air when driving down road) there is but one reason not to do that and it is a retangular piece of paper, Mostly green, with a photo of a deceased ex-president of the United States imprinted upon it. and some numbers in the corner.
The number keeps getting bigger too as the cost of fuel increases.
This debate is always about money, but how much do you actually save? The dash air compressor pulls pretty hard on the motor which kills MPG. The genset which is far more efficient at producing power uses gas. So which is more efficient/cost effective? I have never seen hard analysis on either but I haven't looked that hard. The difference would have to be nominal at best. And travelling with a cooled coach is far more appealing than a hot coach with a cool cockpit. That said I also travel with the fam and they like to use the couch, bedroom, bathroom etc while travelling rather than being confined to the cockpit. I mean to me that's the benefit of owning a MH. But that's my personal opinion and to each his own. I am not knocking it, I just don't believe that it really saves as much as people think it does.
