Sorry. I didn't give enough details. We will be a family of 5 in the heat of Utah and Arizona in June so AC is a must. We have budgeted for the RV campgrounds with electric. We will be out during the day touring the National Parks but I imagine the AC will run while we are traveling like the long stretches between the Grand Canyon and Arches and then Arches and Bryce/Zion. Total side note- I am a she but my husband is the primary driver. I am the planner and budgeter. I have found all of your information information interesting and helpful. Every time I come up with another question, I think "I need the ask the guys (and gals) on rv.net. We are looking at a trip of a lifetime and you have helped make that happen.
