I have said before that i think it would be a great van for local work...but in the current wheelbase it is a van...wait for the long wheelbase and then you will get those bigger loads that go into the sprinter type vans..I have 6ft of personal area and can still get 8ft of cargo in and if need be, I can turn that personal area into cargo area and have 13 ft to use...along with a 6 ft side and read door opening....
Buying a standard length WB van just limits you too much...yes the hightop helps, but the restrictions yo put on your ability to haul bigger longer freight and still be comfortable, is what you need in this business today..especially with more and more carriers turning away from CV's....
I'd wait for that longer WB..as for the aux battery...there is always somewhere, me i pulled the pass seat, installed a Frig, microwave and 2 aux batteries..for the most part, there is never anyone other then me in here..and if there is, they can ride on the bunk or in a folding chair...
