Advice on purchasing a used class B

We were researching used class B's and mostly focused on Roadtrek or Pleasure Way, when a friend mentioned Great West Vans, I was intrigued, as a former Winnipeger I thought it would be good to check out a Manitoba made product. I never got a chance to see a GWV because a few days later an Airstream Airstream (which wasn't even on my radar) popped up locally at a great price and I bought it immediately. Our AI has many of the features we were looking for and we continue to improve it to our needs. This was 3 years and 20,000 miles ago and I havs no regrets having made the snap decesion to purchase a "B" I hadn't previously considered. My purchase advice, if you are in the used market, is be ready to jump on the first one the checks most of the boxes on your list. If buying new you can be more particular. It appears the only way to get everything you want is Advanced RV but the wait list there sounds substantially long. Maybe we didn't get everything we wanted with our purchase but we did get most of everything we need. Happy shopping.
