Easy to build.  Built Ford tuff and critter resistant, maybe not bear proof but sure don't have worry about other critters!!!  Love this thing.  Forget the written directions.  look at the pictures and set out the parts and begin the install.  The written instructions will only confuse you to the point of stopping and drinking margarita's or beer and leaving the boxes for someone else to put together.  After I just looked the parts and the pictures it all came together like an easy puzzle.  Then I sat back and enjoyed my favorite beverage and a cigar!
