Newbie towing question posting again

Here's my Liberty with our 3500Lb dry weight Fleetwood Pioneer 18T6. On the freeway this is the most terrifying vehicle arrangement I've ever driven. If we're passed by anything larger than a full size van we get pushed all over the road (yes wdh and sway bar). 4000 rpm @ 50 MPH sounds about right for any decent grade (thats' where mine was), I had power left but 500 Lbs lighter than your setup.

After receiving some Very good advice here on rv.net, we're in the market for a 2007 and newer Expedition as it has the 6 speed trans (older versions have 4 speed). Having lived the Liberty towing experience yourself, you know all too well how important having an extra couple of ratios in the box can be.

Also note being that the lib is physically darn near the same size and a grand Cherokee (there really is only a few inches difference in each dimension), you won't be reducing the 'frontal area' by using a GC. This is what hurts the Liberty trailering experience the most. It's like standing on the deck of a tall ship in a monsoon, you're going to get tossed around, period.
