I would say a van mount,... 2 pumps, two reels....
i have always said that two people never double the amount of work one person can do,... unless you have two vans.
but lots of people work in pairs, i had someone with me for a while and i found we worked quicker on seperate houses, but obviously you cant do this all the time.
oh and get the largest tank your vehicle can comfortably carry.
