Tom, I know you wanted measurement and sorry I afraid that since my coach has be setting about 2 weeks it will not be accurate. My drive way has a slant down to the storage and the floor is raised for water drainage away from the doors and as long as do not release air out of the tag, which I have learned not to do anywhere, it want drag.

Ron will be your best bet. Good luck and I'm sure your storage will turn out great. Being you have a large hitch on your coach it might be lower than most of our 10,000 lbs hitch.
