Congrats on the combo it looks great, BTW it is exactly like my 1500. Put your mind to ease, I have had mine on some pretty big hills loaded and not had any problem. When I towed to Norwalk this year I had trailer.....4000lbs, car 2400 lbs, cargo in trailer misc 750lbs, and to top everything off I hauled a 1000 lbs golf cart in the back of truck, the truck handled it beautifully. Just use your sense about you when towing and realize 70 mph is plenty fast enough. Oh yeah for all you doubters it breaks every bit as good as my 05 2500 4x4 diesel did. The comment made about an inflatable bag inside the rear coil would probably be ideal for them.
