There are too many variables to give you a cut and dried answer. Carthan is correct, it ain’t much. If your Ventana scraped, you have a LOT of earthwork to do to even think about putting a Newell in there.

It makes big difference if you have a straight on approach. Any turn going into the driveway significantly causes the coach to tip in the turn reducing clearance. Also if there is a drainage swale at the street as required by some jurisdictions, then the dip has to be accounted for also.

Tom can chime in with the pitch of the drive into his garage, but keep in mind his slope is a very straight in and out.

And to make it more difficult, No two Newells are alike. The trailer hitch arrangement can be quite different from coach to coach.
