I totally disagree with you. I own a fleet a gm trucks and I can't begin to tell you how many control arms, pitman arms, tie rods etc, I have gone through. Me and my crew, plow more than you and have been doing it much longer. In fact, I just replaced all of the above on one of my trucks with only 14,000 miles. Another truck was in yesterday for service and they told me all of the same things were bad again. I just replaced 12,000 miles ago.
If torsion are the answer, why don't the Kodiak's have torsion bars? Why did GM drop the torsion bars on the 2007 1500's? Torsion bars are terrible and no way as strong as the twin I beam. Ok the ride is not as good with a twin I beam front end, but so what. I want a truck that I can hang a plow and not have the plow be only two inches of the ground. Try and angle a 81/2 foot plow and every time you hit a bumb the plow smashes the road. You can put the 81/2 to 11 foot bilzzard plow, which weighs 1100lbs, on the front of a Kodiak and the front end hardly drops an inch. The kodiak also rides failry nice, has greater visibilty, and turns around 100 times better than any of my 3500 dually's.
My salesman always tells me that they have people weekly walk out the door when they tell them they can't put a plow on a dmax crew cab. He also goes the the truck meetings in Atlantic City every spring and the number complaint and topic from all the northest dealers is the front end. The dealers ask when they will have a front end that will hold a plow with a dmax and GM says the same thing every year, "We are working on it". That to me is sad to know how many potential trucks GM could be selling.
Also, the plow prep warranty excuse you used is a joke. You are worried about blowing you tranny, what about the regular cabs? You are worried about cracking frames? Gm offers a plow prep package with a regular cab, and they have exactly the same front end as a crew cab. Is GM worried about blowing a tranny with a reg cab? If the front was stronger, then it would not sag as much, which would keep the truck more level and there would be a lot less stress on the frame, in the end reducing cracking.
As for GM having the best front end in the industry, you are way off. I am GM guy, but the facts are the facts. The front ends suck. I am glad you have had good luck with your front ends, and I hope you never have issues. However, if I wanted a nice riding truck to work in then I would get a El Camino. I do not care if my head bounces of the roof when I go over bumbs.
GM has an awesome diesel engine, awesome tranny, nice interior, nice 100,000 warranty, but a bad front end, for what I wan't to do with it.
Also GM's front GVW 4800lbs. Ford's front GVW 6000lbs. BIG DIFFERENCE!!!
