I heard that in 2007 Allison came out with a dual shift profile. One that up shifted quick for when you were just cruising and another that held out the upshifts longer for when you were towing. Has anyone ever heard of this? That would be nice to have. I now have to break 50mph to get into over drive and there are many times when I would like to have that much lower.
I also heard the 2007s Gulfstreams had a beefier sway bar in the back?
A concern from the Kodiak Yahoo group was the Duramax cooling fan shredding itself and causing lot of damage under the hood and to the hood. It's a good site to follow for the kodiaks - lots of great information on all the makers.
GM made a change in the fan, but not sure when. Our 2008 has the new nylon fan assembly and it is electronically controlled.

We are retired fulltiming in ours flat towing the Jeep. No mechanical issues but the dash gauges can get silly. There is 34k miles on her right now and had less than 2k when we bought her in 07.They come with a 10k lb. hitch also. Been over 26k lb. towing racecar trailer and full water tank. Originally from Denver, Co. area currently in Pacific Northwest. I'm not a Chevy guy but I like this rig.

I think as an rv chassis you really need to watch the weight. We looked in 2005 for a funmover type motorhome to haul bikes as well as people. In 2006 we test drove a Seneca. I watched in horror as I drove down a Vegas freeway with my wife sitting in the slideout couch, flexing and bouncing with each jolt!
I looked at the gvw and it was not enough to do what we wanted done. I think there was 1800 lbs capacity if I recall. Now you throw in fuel, water, couple of people, you don't have much left.
We went and looked at the f750 based chassis Funmover instead. It's much more solid on the road tho' heavier... and slower. Same hp, more weight.
We tow our 26' Joker Powerboats raceboat (4200 lbs.) all over the country with our 2006 Gulfstream Ultra 33'. Has 8.1 (496) with Allison transmission. Can't tell the boat is even there.

We just did a move across the state of FL in our Super C. I never thought I would say "Don't put it in the RV, there isn't enough room in there" but I did several times because we had so much stuff packed in that RV. And we have the unit with the large under bed storage! (only one slide) When it was packed to the hilt I had a 150lb floor jack which I shoved in as hard as I could just inside the back storage and then dropped a 28' long 10' beam Sea Ray cabin cruiser (8000lb, 500lb tongue weight) on the hitch.
The unit actually handled better! The rear didn't even sag because it sits on the rubbers above the springs. I'm thinking of getting those air bags in there so I can get that kind of handling on a light load. The 8.1 had no problem keeping overdrive through the hills in Pensacola on I-10. That motor's powerband is between 2500-3000 so you need to keep up a 70mph speed to keep the motor in its band. the diesel would allow a slower speed and still keep OD.
Can't say enough good about that chassis, its unstoppable.
