We purchased our 2019 Thor Aria 3901 in June. We live in Utah and have traveled to Wyoming, Kansas, Oklahoma, Texas, New Mexico and back home. We love it. The size is perfect for us. Both my husband and I drive it. At first I was worried about driving something 40 foot long, but I did just fine plus pulling our jeep wrangler. I love the king bed. We didn't like the mattress it came with, so I replaced it with memory foam. With the slides out it so big and comfortable, and having the theater seating with the TV directly across was something we had to have. We have some minor issues that need to be fixed so right now it's at the dealer. But I miss it and can't wait for spring to go out again.
