Have owned several van conversions, whole bunch of Tahoes, Suburbans, Subaru's...a Sienna my favorite of all of them for non heavy winter conditions. Plenty of power, so utilitarian. Put a camping cot and several surfboards including a 10' longboard for summer coast runs, sheet of plywood when in project mode. The reason they went to run flat tires on the earlier models is they had no built in spare tire holder. Friend with an earlier AWD went to winter tires, kept a spare in the back. He also installed a mild lift kit so he could run the beach (surfer), and he'd fly through sand I was unwilling to take my heavier 4x4 rigs through. In 2008 they went to timing chains instead of timing belts.
