Once you get familiar with the directions and parts you will be surprised how fast just the benchwork all goes together (not sure about the lift gate?). I think you will find it kind of fun to do after you get a couple of pieces put together. It's not like real carpentry or woodworking stuff and it's all light weight and easy to handle. Oh, and no sawdust!
I would offer to come help, but you will probably be finished by the time I get there, don't want to spoil all your fun either.
