Stop in for a cup of coffee

Here I am hunting for a hot rod for me and my Brat sends me this.

"I have a task for you. Troop 2567 wants to find a cookie mobile. Like an old U-Haul we can put a window on so the girls can sell out of it. A retired ambulance, ice cream truck kinda thing. We would need it operable by Jan and we would use it every cookie season".

No mention of where the $$$ are supposed to come from. It is a rather creative idea, but funding the project is not on my "to do" list. I'm not all that familiar with the Az registration requirements either.
Okay forget that unless they has the funds… that said, a dodge panel van with a hemi would be cool
