Jack,
Tell the truth. You just take delivery of your new three slide Liberty H3 Elegant Lady with (only) four Cruise Airs and you head out to the desert in August.
What will your first reaction be when you find out you are working your fingers to the bone pressing buttons to cycle the AC units on and off so you can keep the inside of your new pride and joy at a comfortable 90 degrees after you just traded in a coach with OTR?
I'm pretty sure even if they all worked as they were supposed to that 4 Cruise Airs will not cool that much interior with the slides open. Remember, these coaches aren't the white Winnebagos but are the fashionable dark colors.
It will feel like the North Pole when you jump in that coach after standing out in the hot desert sun, but after being in it for a little while and it can't get out of the 80s inside I can just see the new owner going ballistic.
Nope......five roof airs and an engine driven generator.
