WTB Used FS - Southern MD <$4k

I am interested in buying an older FS for under $4k. I have a steep driveway and am wondering if anyone that owns a FS may be able to comment on the limits of the trailered FS to be backed into a steep driveway from a level street and Sidewalk. Dimensions of a trailer set level from the hitch to the center of the axle, and from the center of the axle to the back bottom point of the boat would be helpful. How high is the bottom of the stern of the boat off the ground when the trailer is set level?
