The answer, IMO, is whether you will need to have all work done by a dealer or whether you can do much of the work yourself.
I have a friend who is definitely mechanically challenged. It would not be good for him to depend on his abilities to do the work necessary to keep an RV in good shape. In his case having a dealer near would be a necessity.
I had discussed with a relatively near dealer about him doing warranty work. He said that the people who buy from him go to the head of the line. He said he would do warranty work, but I needed to be aware of his priorities. That being said I had to get the some electrical work done under warranty, and he had the trailer all of two days. So it worked out just fine. I live near Kansas City, and bought our toyhauler in Knoxville, TN.
