RetChief

I'm not a businessman but I'm pretty sure if I was trying to sell a product that works "half the time" I don't think that would be a very good endorsement of my product. I think I'll wait until they offer a DFM disabler that works all the time. Hopefully they figure it out pretty soon.

I spoke with with the the folks at RANGE about a month ago and was told the DFM disable module is not compatible with the 10 speed transmission. They stated they're working on it. You got an 8 Spd your good to go.

Not that I've heard. Neither of my two trucks, both SU5 frt axles, have made any noise or music.

When you find a truck you like just ask the dealer to pull the Build sheet up. Takes 5 minutes and don't cost anybody anything. Sheet will have a bunch of alphanumeric codes listed. You want Frt axle code SU5 which is the GM sourced axle.

Don't mind the firm seat bottom but that vibrating thingy makes me feel like something is in my back pocket. More than once I thought I left my cell phone in my back pocket. I recently retired and I rode a motorcycle for a living, to me a firm seat is more comfortable than a soft squishy one over long distances/times. I gotta figure out how to remove the vibrating thingy.

Im 6'6" no problem in or out unless I use the running boards, then I get too scrunched up to get in or out. My wife uses the the running boards otherwise I would remove them.

I don't regret it. I tow a small utility trailer with motorcyles or small boat trailer. If I was towing a 5th wheel or a bigger boat I wouldn't hesitate to get the 6.2 but I honestly can't justify it for my use. Premium is 80 cents a gallon more around here. I don't have a problem merging/passing on the freeway but have to admit that 6.2 is a beast in a good way, I just don't want to pay for just the fun factor of it. Think I might go look for a bigger boat.

Well there you have it. Thanks new dude, Now I just hope my rear window don't leak.

T1 GMC and Chevy 4x4 trucks use one of 2 front axles, AAM and GM sourced. SOME owners of the AAM axles are having issues with the front axle making noise. My main concern is that GM seems to be struggling with coming up with a fix and I don't want to drop 50+ large on a truck and hope I don't get a noisey axle, that there's no current fix for. Thats why I searched for a truck with the GM axle. I think GM will get it figured out at some point I mean its an axle.

I've decided on a 2020 AT4 put down a deposit a couple days ago. Truck is in transit. I decided I would only buy one that had the SU5 (GM) front axle not the SU4 (AAM) front axle. I found a couple trucks that were optioned the way I wanted but every time I had the dealer pull the build sheet they were built in Mexico with the AAM axle. Now I got nothing against Mexico my problem is with the AAM axle. I found a carbon black metallic AT4 that started with 1 in the vin so I know that's built in the US. had the dealer pull the build sheet and sure enough it had the SU5 axle (GM). So I bought it. As I looked around at other carbon black AT4's at various dealers all the carbon black ones I looked at were built in the US. So.... my question is does anyone know if carbon black metallic AT4'are only built in the US.

Took a couple weeks to get used to my seat, but its all good now. Seat is a little firm but not uncomfortable. After numerous adjustments I think I found the sweet spot. Got a 2500 mi trip in a couple weeks, that will be the real test. Hope you get yours sorted out.

Switching to Dodge aint gonna work. My wifes Durango does the same thing. Happens every now and again. Just had the radio replaced, still does it. Pick a manufactuer they all got bugs.

Haven't noticied that on my 5.3 Just getting warm up here in the frozen north. Maybe routing is different. I would think a little extension on the drain hose would cure it.

Just had Nav installed yesterday. 2019 RST with IOS radio. Truck came with SD slot in center console. 45 min at the dealer. Works great. The nice lady I spoke with at GM tech said it would only work with IOT radio. Little disapointing the Tech folks are not up to speed on their own product.
