Gene in NE,
Yep, 10'-2" was the common height of most B+ units. Even the longer Phoenix Cruisers built on the bigger E450 chassis are 10'-1". We had very little to choose from in the used market, which steered us into this new one. In all my search over a 7 month period, there were only 3 or 4 used rear corner bed models to be found. But they were all expensive Isatas. Our Phoenix Cruiser brand new, cost only $10k-$15k more than their 5 year old used ones with 20k to 60k miles. We got a full warranty and got the RV made to our exactly specifications. It was well worth the extra cost.
I am 5'-10" and our model 2350 interior ceiling height is plenty high. Given the width and length are not all that much, a lower ceiling height shows it off in good proportion. Go to my profile and scroll down. I took an interior picture with my cell phone seen there.
A lower Roof has less wind resistance too, though hardly worth noting the difference.
