Re: [A/S] Towing with Duramax/Allison

[Airstream12557@xxxxxxx]

Made my first tow with our new 2002 GMC Durmax diesel with the Allison 
transmission.  Left Florida April 2 and arrived back in Kentucky April 19.  
Drove a total of 2564 miles, used 182.544 gallons of fuel, and averaged 14.05 
MPG.  Drove 65 MPH most of the time and used the cruse control.  The trailer 
is a 1999 27 ft. Safari, and we were heavily loaded since we were bringing a 
lot of unused "stuff" back from Florida.  Truck would hold the speed set on 
the cruse control both up and down the hills.  Would go up most hills without 
downshifting.  The grade breaking of the Allison transmission is great.  When 
slowing down, it automatically downshifts to aid in slowing the rig.  

I also had a Jordan Ultima 2020 brake controller installed.  It is so much 
better than my last electronic brake controller.  It's control reminds me of 
the old Kelsey Hayes hydraulic brake controller, without the hassle of 
adjusting a resistor under the hood.  When I had it installed, they adjusted 
the control level and I didn't have to make any changes.

Also used a set of Hensley clam-on door mirrors.  They are also great.  It 
took me a few trys to get them adjusted to my liking, but after that they are 
in full adjustment when I reinstall them.  Installation and removal is very 
quick.  They extend far enough from the truck that there is a full view of 
what is going on around your vehicles.  I got the convex mirror option which 
is a "must".  They are as easy to install as the "slip on" mirrors that go 
over the OEM mirrors.
