I recommend the grey 20 foot containers from Cape Cod Trailer Storage. I use them on the majority of my construction sites and even suggest homeowners to rent them when they are having me remodel their home. Good prices, good fast service. Rumor is they even have a new truck that can move these containers loaded. Until now, had to unload before it was brought to a new job site. Check them out.
Pros: fast service, good product, low price
Cons: sometimes rushed on the phone
