A standard van would be my last choice.
Doing news, I've used vans, SUVs, cars, a Rand Lover (at least, that's how the bank account saw it, no matter how it was spelled on the emblems), trucks or various sizes and configurations, production trucks, motorcycles and ambulance refits. Each has advantages and disadvantages ("The truck gets you respect, the motorcycle gets you THERE").
For doing news, I found that a small 4WD SUV was the best all-around vehicle -- fairly economical, rugged, more compact and easy to drive than a van, able to leap tall curbs at a single bound (well, MEDIUM curbs, anyhow), with more than enough room for the gear I hauled plus a helper or two. With a luggage rack on the top, even more gear could be carried, and more than one shot over a wall came from the top of an SUV. You may also be able to find one on the used market for less than you would have paid for a van.
If the only reason to get a van is to haul a little more gear (or haul more comfortably), you might want to consider a TRAILER.
A small trailer is inexpensive and can be towed by anything that has a hitch on it (including motorcycles!), and is actually easier (and safer) to get equipment into and out of than a van (the exception being an ambulance with outside compartments). If you get a cheap flatbed trailer, then mount a box on it, you can take the box back off for more versatility, or have several boxes with various kits in them and mount the one you need for a particular job (think Thunderbird 2).
