For crying out loud get a bigger hose reel.
Ordering the 4007 blower and running a stock live hose reel and 2" hose is a serious handicap, make provisions now for 2.5" hose and unleash the potential of that 500 cfm blower.
Unless you seriously have a dumping problem, why would you order a 210 waste tank in a standard van?
at some point a pump out will be a better use of space and money.
Tell em to keep the 10" 3 jet wand, and save that money for a higher production tool more suited to your vacuum potential.
High heat sounds good, but hasn't been running long enough in the field to figure out if blower life is being sacrificed, quite a few blower replacements out there, inconclusive if it's the high heat or not.
