Custom shed is the way to go..I thought I would take advantage of a shed that was built over winter..to take advantage of the savings..not a good thing. the ridge vent was missing along with the plate across the doorway... and from being stored in the field down back all the water run-off through that area the shed was twisted the side door still is not opening the way it should. the rear 4 x 4 was hanging when it was placed on the pad and others twisted. I reported the problems and the way they talked to me this was a normal thing.. and they were fighting with the township so they could get the storage problem taken care of down back. I will have a carpenter do the repairs and install the ridge vent.. You get what you pay for. PAY THE EXTRA..I still like the shed and will get all repairs done.
