Phoenix heat in summer w/Class A coach

You should have no problem keeping your rig cool and comfortable in the heat. I grew up in Phoenix so am no stranger to the heat. We did run all three A/C during the day but only two at night. The reflector stuff on the windshield will help. One word of advice, two actually...make sure wherever you choose to stay, that the electrical is strong, and do not let the heat creep up on you. Even though it cools down at night, if you leave the A/C units off during any part of the day, they will play heck trying to catch up and cool your rig down. Drink lots of water, even though you won't feel thirsty. The low humidity fools you, so force yourself to drink water all day. Make it through the first summer and you'll be hooked on the dry climate and sunshine every day.....Dennis
