David-
My 10 x 20 shed arrived today. I'm very impressed with the quality. The site prep was done last week. The guy asked if I was going to put a car in it and I said No. He said you need to make sure that the ramp isn't too steep for a car. Didn't hink much of it until today - the ramp is too steep to get my old Wheel Horse 520H in it with the mower deck on. The deck gets caught up on the ramp/shed interface. I had to make a 24" long transition for between the ramp & shed (not shown in the pics). Anyhow, if you have any slope at all to your site, make sure to either get a longer ramp or have the guy prep the sire accordingly.
Here it is:
