FYI, a motorhome going down the road won't be "conditioned space". You can run the AC unit in the drivers cabin area, but that AC won't be cooling down the rest of the motorhome... especially in the summer. You would have to run a generator while you are going down the road and turn on the overhead AC unit to keep it cooler, the same as you would a travel trailer.
This isn't universally true. The dash air conditioning is quite powerful, really--more powerful a ceiling RV air conditioner--so it's more a matter of distributing the cool air through the motorhome. I find opening the rearmost ceiling vent a little (I have vent covers, so they can readily be open while driving) helps to suck the air through and usually does a reasonable job of keeping the temperatures under control. Naturally, it does depend a lot on what the weather conditions are where you're going; a 110 degree day is different from an 80 degree one!
