Hello all I am a Florida flat land driver. I have the ram 1500 17 bighorn with 8 hp70 2 wheel 3.21. The wife was out in North Carolina and claims she was on a bit of a hill and had go in reverse and the truck would not move. Now this is a brand new truck maybe had 1000. I don’t have very many hills in fl much less drive them in reverse. Everything works great no signs of trouble. So I am planning on getting a boat has anyone experienced any trouble when backing up their +5000lbs load on a driveway with a grade or any uphill reversing?
