Prevost Garage

After looking for storage facilities in our area we realized that the closest facility to accommodate a 45' bus is about 1 hour from our house and there is a waiting list. We decided that since we have another 2 years before retirement we should build our own garage on our hilly property before buying the coach. Might as well get things ready first so the coach can be safely tucked away upon arrival. Due to building setback requirements we'll have to dig into a hill to get driveway and building fairly level. What slope per foot is recommended for driveway leading up to building? Our questions to you experienced owners is what do we need to look out for and what niceties did you, or did you wish you would have incorporated into your garages. We were talking about possibly including a separate septic system if we can get the permit for it. What is the optimum width, length and interior height of building? Do H3-45 require a higher than 14' header on the garage door? Best size and width of garage door? Concrete floor with slight slope towards garage door to allow run-off from a wet coach to drain outside, or is it better to have an actual floor drain in the center of the building? What PSI rating do we need on the concrete floor?
Your input would be greatly appreciated.
