Want to open small drive-thru or truck based espresso biz

[byergo]

I would like to hear from operators (no salesman or consultants) regarding the best route to go, best equipment value (factoring in quality), best bean supplier, best cup supplier, best truck supplier, best drive-thru building supplier, etc... I want to set the biz up in the parking lot of a major retailer with parking lot road frontage. High traffic location.

If you were starting over again would you buy a truck which can be moved to different locations, or a fixed small drive-thru building set up? I appreciate any and all info.

Thanks!
Scott
