I currentl have an 03 Dodge 2500 Cummins Diesel pickup and it has no problems pulling my boat. The problem is it rides like a stiff legged mule and my wife refuses to ride in it anymore. (I know for some of you that isn't a problem but I like having her around!) I am looking for something that can pull my 21' aluminum Jet Boat that when full fo fuel and fishing stuff, weighs, I guessing just under 6000 pounds. I know the AVE is rated for about 7000 lbs but I pull my boat through the Idaho mountains and do not really want to be at the head of a long line of not so happy people following me. Have any of you had any experience putting the new 5.4L to the test? WIll I be sorry? I test drove one and really like the ride. I thought about a 2500 but I am sure the ride suffers as well as the fuel economy! Thanks in advance!
