Hi SnuffySmith! When we bought our AS, we went with vintage because we liked the lighter weight and have "project" addiction. Not for everyone, we know. However, our 31' really does need the WDSC even with it's lighter weight. We've taken 2 trips from Texas to South Dakota/Iowa, and know first hand how gusty the wind can be on the plains. Love our ProPride. (We're long-term Texans. Moved here from Orange City, IA)
Since plenty of people have offered opinions on AS, let me give you some info about establishing residency in another state. The states chosen most frequently by full-time RVers are Texas, Florida, and South Dakota. Their popularity is due in large part to no state income tax. When it comes to state sales tax, Texas is 6.5% with no tax on food. If you buy an Airstream, there are 2 Airstream communities where you can purchase or just rent a visitor lot. Texas Airstream Harbor is on the shore of Lake Sam Rayburn.
A good resource for learning all the legalities and other concerns of becoming a full-timer is Escapees. Their headquarters is near Livingston, TX and they have several RV communities including a new one by the Black Hills, SD.
