I am still at it. I have a 2004 Dodge Quad Cab 2500 which came with a factory installed Class IV receiver. I recently bought a 2004 Airstream Classic 31. It came with a Reese High Performance Trunnion Weight Distributing kit.
After trying two different Reese hitch bars I am unable to get the ball height down to the recommended Airstream ball height of 18 3/4". I can get it to 19 1/4" or 18 1/4". It is 1/2" off either way. Airstream factory says that is not acceptable.
It looks like I am in a quandry. I talked with a Reese tech person a while ago. The Reese reciever recommended for my vehicle is PN 37089. However, it will not fit a vehicle with factory installed receiver.
Any thoughts or counsel would be tremendously appreciated. Has anyone else had a similair problem? Will being off 1/2" have a negative effect on my towing the Classic? I will be on the road a lot with the set up and want to get it right.
