Bro,
The first vehicle I drove after I got my DL, was a passenger van, a
Nissan Vannette. Though I agree with you that van does not have the
front bonnet, you can easily drive it straight also. When doing the
parallel and vertical parking, you got to quickly recognise which
part of the van to substitute it for your rear small window of the
car.
In fact, driving a van gives you a panoramic view of the road. Its
higher that a car and you will feel comfortable.
Build your confidence fast and in a matter of time, you will like
driving the van more than the car. Only 1 thing you have to
remember, don't drive fast.
CHEERS!
