After about 5 motorhomes, I have some comments about wheelbase and handling. My previous coach was a Vista 30W (earlier version of 30T). It was somewhat squirrely. Did the CHF, helped some. Played with CHF and air pressure. I then became interested in the 30T to pick up on some of the new features. Along the way I found a Sightseer 33c. More room, 22.5 tires and a better wheelbase to OAL ratio. It drives amazing and I had a real test on the I-40 between Amarillo and Flagstaff. In checking the chassis, it appears stock. My conclusion: weight, wheelbase, and the heavier chassis make a difference. And I found a 2016 model priced under any 2017 Vista 30T's that I had researched.
