Was able to put this together by myself.  Was pretty easy if you follow directions.  I still need to put it on a level base but decided to try pallets to save time and money.  Not as big as I would have hoped.  Should have gotten a two-door style as some of my equipment will be able to fit (and taken out).  
Originally ordered the 4 x 6.5 and was sent the wrong item.  Too much trouble to send back.

Pros: Compact design.  Sturdy
Cons: Size
