I tried searching this forum using "tall" as a keyword and got a couple of hits for threads which
might help a bit. Some of the other folks on here are also dealing with how their physical height
creates other interesting issues. You might want to ask them via posting, or PMs, how they
deal with the "I'm a tall person, which van works best" questions. Most folks are happy to help,
if they can.
There are quite a few threads on the subject of maximising storage, and you can keyword search
it too, from the little "search" window in the top right corner of most of the pages on this site.
Some people have made some pretty cool mods to their vans, and some have chosen to add external
carriers, to increase their travelling storage capacity.
Anyway, good luck.

of the other advantages of a "B", some of which you've mentioned
Was down in the Boston area last August, but just passing thru on a Sunday afternoon.
The traffic out to "Cape Cad" was unbelievable. Turned around and headed back west and stopped
at a mega-mall with all sorts of stores including a Walmart and I think a Home Depot to name a few.
It also had a Starbucks, so we stopped for a cafe before heading home to the Niagara peninsula in Ontario.
Can't remember the name of it, but the mall was huge. Started with a "C" the name I think. Just off
a State Road on our way inland towards I-95 to jog north a bit, to then pick up I-90 west.
Nice area, around and in Boston.
