cargo van additions

Ram Promaster cargo van, converting to a campervan. I'd like to keep the aero clean, and not make this tall beast any worse than it is. I'm getting about 25mpg, diesel. I'm not going to put the typical awning on it. However, I'm finding it hard to resist the roof fan. They are about 15x15, one would be only 3" high flat top (fantastic fan with flat top), 3-3/4" rounded top (maxxfan standard), the most aero looking one is 5" high (maxxfan deluxe).
Any educated guess as to how much of an impact this will be?
