2012 Yukon not seeing trailer connected
I have the factory integrated brake controller,(JL-1) this is the 1st time it's being used as I had to connect the red wires to the studs. Fuses are good, I have 12V at the studs. I have 12V at the brake control relay or module located above the spare tire. The blue wire is good between the module/relay to the 7-pin, and both sides of the 7-pin are clean. No stored codes. Trailer works on another vehicle, and the Yukon still doesn't work on a 2nd trailer. I have also tried a new GM gain switch and module, still no change. No error messages, but the Yukon still won't recognize when a trailer is connected. Curious if anyone has dealt with this.1.2KViews0likes4CommentsRe: Question on changing legal GCWR

GV Thanks for the replies, sorry to reply so late, I'll try to touch on everything. I did reach out to GV and they said there was no option for a 8.1 Burb with 4WD, only 2WD....but that option would be great with the 4:10. My plan was for weights around 11-12K, it would be a boat. The haul would be short, less than 20 miles. To correct my error in GCWR, it is 17K (not 16K) & 19K for the 3:73 & 4:10 respectively. I guess my initial worry was if there was an accident, and I had the factory 3:73 gears and was towing 11K and still within the GAWR of both the TV and trailer, would I possibly be denied insurance coverage if they ran my VIN and saw the 17K GVWR. So it seems that isn't really the case as it comes down more to GAWR, tire and wheel rating, and trailer rating with trailer tire and wheel rating. I would prefer to find a 4:10 Burb and add the GV for unloaded highway travel if that option was possible. I guess the 3:73 would be fine for short trips. I've found a few 8.1 Burbs but some of the prices have been crazy high. Been alot of flipping recently by a few outfits but hey, free enterprise. I don't mind the logistics involved with locating one, as long as the body and undercarriage is good.659Views0likes0CommentsQuestion on changing legal GCWR
While looking for an 8.1 Burb, I come across some 3:73 models which have a factory GCWR of 16K. Since the only change to the GCWR of 19K with the 4:10 models was the gears, has anyone changed the gears to increase the legal GCWR? By doing this also with documentation changing the legal GCWR? The GVWR is the same 8600 LBS with both axle ratios, only the GCWR changes. I understand most agencies won't pay much attention to more than the tow vehicle GVWR, trailer GVWR, and tire ratings. I'm only looking to maybe change the legal GCWR if it came down to this. If anyone has gone through this successfully, please share your thoughts and experience. Thanks.4.2KViews0likes16CommentsRe: Considering 2012-2015 Suburban, have a few questions

With the 6.0 and 6 speed auto, ur hwy mpgs should be 17-18 or so... I get 17 mpg at 70 while driving my 2009 2500hd with the 6.0. That’s my take... get the low miles with the 6.0, even pulling a small camper your still fine... Does the 6.0 suffer the same AFM issues as the 5.3? I agree the 8.1 is a great motor, and after looking into the later 9th gen 2500's they are appealing. I wish the Burb had the cooled front seats, I have another thread on this, but not a deal breaker. Since it's an option on the 2500 Yukon, I wonder if the Burb is wired for it.728Views0likes0CommentsRe: 9th Gen 2500 Burb...cooled seat option?

APT wrote: Option only in the GMC Yukon XL 2500 SLT. If you are looking at pictures online, check out the front doors where the switches are for memory, heat, and cooling. I'll look into that. Haven't seen a 2500 LT with them, wonder if it could be installed...I prefer the front end of the Burb but not a deal breaker.298Views0likes0CommentsRe: Considering 2012-2015 Suburban, have a few questions

Sorry, should have added that the 5.3 would be for "only" the family hauler. Wasn't well versed on the AFM 5.3 models and what to avoid.729Views0likes0CommentsRe: Considering 2012-2015 Suburban, have a few questions
So this Suburban debate has now taken me back down the 8.1L path and part of me is still leaning towards a 4:10 model. The 2013 2500 6.0 is one I shouldn't have looked at, :C the clean, low mile ones just look great. There will be occasions I will tow around 10K, if we end up with a boat that may stretch to almost 11K. The boat is not entirely in the cards but with either one I purchase it will not be the daily driver. I like the simplicity of the GMT800 2500's, but the 900's are very well rounded and the tow rating would suit 90% of my needs. I've found a few very nice 2500 800's and the prices are surely creeping up. This will be a hard choice, either a 2015+ 5.3 highway family hauler, or a thirsty 2500. Man I wish GM did a GMT900 with the Duramax or a stroked 6.0 and gave it a 12K rating. Would have been possibly the ultimate tow vehicle IMHO. Tough call when a cherry 100K mile 9th Gen 2500 8.1 is almost the same price as a 150K mile 10th gen 2500 6.0.729Views0likes0Comments
