Hernan, my son has a van very similar to this.
His one does not have the large lump over the driving cab.
Makes it a lot faster and better fuel consumption.
I just sold my old 1995 Fleetwood, loved it, drove it to death, now I want a new one as well. They are a lot of fun, the dogs can have their own spot and the wife can lounge with a book while you drive down the road with some tasty music playing.... ahh, get one for me too! :O)
