I have the plans largely complete for a new bus barn and am planning on building a pit. I have reviewed as many of the old threads that I can find but find no reference to the length needed for the pit. It appears that two feet wide and four feed deep is sufficient, but I don't know if I should plan a pit the length of the bus or just a partial length. I know that some of you have gone through this process. Please share what has worked best for you or what you would do different regarding size if you had to do it over. Thanks.
