I replied to your previous post but some how lost it LOL.
I will be towing a Prius behind any RV i get. I worried a Class C would be too small to carry My Fishing, Astronomy Metal Detecting and Scuba Gear so been looking at Class A.
When I did the Try Scuba Class the Instructor kept laughing when ever I surfaced from doing what she told me to do, Finally I asked what I was doing wrong and she replied it was not me but that Smokey would pace and touch the water every time I went down (Never tried to enter the water). By time I got to the point of staying underwater for 20+ min Smokey stayed laying down playing with a toy next to where I went down. and the longer I was there the more relaxed Smokey and I as well were.
