Ok.  We have purchased our tow vehicle.  2008 Ford F450 2 wheel drive.  Doris even test drove it and feels she will be able to handle it.  Loaded with pretty much all the options you could want and more with low mileage.  The hitch gets installed on Tuesday and have the itch to tow with it to see how she does.  April of 2011 can't come quick enough!!

Congratulations, you have chosen  a very capable tow vehicle.Don't think you can go wrong with it.
