Now folks, maybe, just maybe, these new buyers of a Keystone loved the floorplan and have seen similar units on display which convinced them to purchase.
When I bought my Outback 5er, winterizing was never a thought and it was not brought up. I met with the division head of Outback along with the dealer at the RV Show in Louisville and bought the show model. It has served us very well. As I age, now 70, it does require more effort to crawl under that rv. (and yes, I am in good physical shape). So, I have found that the newer models now have made an effort to make the winterizing and draining of tanks, etc, a more tolerable task.
Would I buy another Keystone without a newer set up; you betcha. BUT, there may come a time when a different system will be a MUST.
To each his own.
