It's like you are reading our minds. Those are alll reasons why we upgraded. I had a bad experience the last time we set up in full sun. I remember my friend picking me up from the ground. I just turned 50. Some say the trailer is a mid life crisis. I see it as years of less work.
On our maiden voyage, we stopped at Zaxbys for some chicken. I suggested we get the dogs out of the truck and eat in the trailer. My wife loved the experience. Much better than eating in the truck. It only got better once we were up the mountain and set up.
So far I am very happy with the Flagstaff. I think one of my first upgrades is going to be LED lights. We frequent US Forest Service campgrounds that have few 120v AC hookups.
