^^^^What he said

 

I towed a 1983 Landcruiser diesel loaded with spare parts on a tandem uhaul car trailer (total was almost 6000lbs) and towed great, same setup as you. Not going to get 20mpg on the highway. I was much happier with this than my 2009 5.3 w/3.42

You really set yourself up for a lot of blow back when you make a blanket statement like that. My throttle response is awesome, see what I mean?

I have the 5.3 with 3.42's and I tow a 18' steel deck car trailer, loaded with two RZR's. It pulls just fine.. I have a 04 Ram with the Hemi, same set up and it's a dog compared to the chevy.

 

I've had a mid size SUV on the trailer with the chevy too, no problem. The only complaint is with a heavy load the MPG's goes to shit 10-11 MPG.

I towed our Boy Scout Troop Trailer across the great State of Louisiana and back over this last weekend. The trailer is a 6X12 single axle enclosed cargo trailer. This truck is a pulling / towing beast compared to my 07'. No problems accelerating, even when I forgot to put it in TOW/HAUL on the return trip. My truck has the 5.3 and 3:42 gears. My previous truck pulling the exact same trailer with a comparable load averaged 12 going and 11 mpg coming back. This truck averaged 14.2 going and 13.1 coming back. I attribute the loss to head wind.

So my trailer is 7,500 (scale weight) with passenger's items & equipment total is more like 7,900. Manual Max towing says 8,600 but and I can't find in manual where it list conventional towing but it is on the gmc site @ 6,600. I use a WD and sway control bars and truck is SLT 4x4 crew cab short bed that came with trailer sway control, integrated trailer brake, oil and trans coolers, hitch, and plug wiring. Didn't think it would come with 3.08 gears. So far it pulls alot better than my 2007 but worried if I am exceeding limits for both insurance and reliability issues. As far as safety, it has same suspension and brakes as lower geared trucks so not worried.

Not sure I follow? First, passengers usually reside in the cab, so you can leave them out of the trailer weight but keep in total weight. Second you seem properly equipped for your max rating of 8,600?

Very interesting. Just looked through the 2014 trailering guide and I couldn't find 8,600 listed for any truck configuration? In fact, everything I found for your truck listed 6,600. Makes me wonder if it isn't some sort of misprint? Unlikely, I know, but 8 is awful similar looking to 6.

I wonder if there is a difference between "Maximum Trailer Weight" & "Maximum Conventional Trailering"? By adding the Weight Distributing" hitch, can I now tow 8,600? If it's a misprint and my trans goes out before 100,000....it's on GM. If I get an "update" to the owners manual with lower tow ratings I will see about GM changing gears to one set lower.

With 3.08's its 6600 or 6800 with 3.48 it jumps up to I believe 9800

I keep seeing everyone say 6,600lbs. My sticker shows 7,200lbs. and I have the 3.08s in my truck. Is there a reason for the difference in that?

6600lbs per spec is max tow rating for your crew cab short box 3.08 4x4. 3.42 would be 9600lbs.

That is the GVWR (Gross Vehicle Weight Rating) not towing capacity.

Got it. Thanks for the clarification.

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
