We're on a trip around the US (in Mississippi at the moment) and do run the generator several hours a day while traveling to run the basement AC. Much better to arrive at a camp site with the entire inside of the RV cool. We have traveled using only the dash AC and when we get where we want to go the living quarters take hours to cool down. I do turn off the dash AC and also run one or two fans to help circulate the air inside the RV. This works great for us.
