I am a potential new owner. My driveway is fairly steep when first turning in and out. I am getting grading work done to accommodate driving in and out with my very good potential Kountry Star 1998, Diesel, 38' unit. My questions concern bottoming out the rv and how to figure given the wheel base length, ground clearance, turning distance and section rear of the wheels with the angle of the driveway when turning in to not bottom out. I would rather think it through before starting the grading process so that I don't have to call a hook. Any comments?
