  1. I have driven all the variants. My gotta have are the 18 or 20" tires and power folding mirrors. The rest of the items I can live without. #iworkforGM
  2. I think it's either the width of the box or the distance from center of ball to front. I would start with center of ball measurement. #iworkforGM
  3. I would try 2 inches to start to make sure it changes something. #iworkforGM
  4. You need to adjust some of the measurements. I would take a look at the dimension from center of ball to front of trailer. This dimension usually gets messed up because instructions doesn't explain it well. You need to pretend the it has a flat front on the trailer. It looks like you need to increase that number. #iworkforGM
  5. The final redesign hit flint last week. Not sure of its availability at dealers yet. #iworkforGM
  6. On diesels, it is rear leaf springs, rear axle, rear shock, and rear tire pressure increases to 80 psi. On gas models, rear axle is same. #iworkforGM
  7. The problem you have with pickup campers is going over FGAWR not your payload/GVW. That is why most camper packages have higher front spring rates. The higher front spring rates are good for roll as well. #iworkforGM
  8. The thing to remember is there are only two numbers that are VIN specific on the trailering label: curb weight and payload. The max conventional, max gn, and tongue/pin weight are based on SAE calculation. SAE calculation uses base vehicle mass for heavy duty trucks. That means your max GN / fifth wheel is likely significantly lower if you have denali/high county. I have seen situations where the max pin weight is actually higher than the available payload. #iworkforGM
  9. The problem with going down to 5200 is it may not trim properly. You may not have enough adjustability in torsion bar adjuster based on your front axle weight. #iworkforGM
  10. This looks correct from 2020 to the mid cycle. #iworkforGM
  11. 2500 diesel crew cab runs 5600 FGAWR.
  12. The F60 - heavy front suspension / camper raises your FGAWR by 400 lbs (next size up). VYU - snow plow prep / camper raises your FGAWR to 5600 lbs on gas engines and 6000 lbs on diesel. On a lot of 4wd diesel models, F60 and VYU get you the same suspension. #iworkforGM
  13. 4400 FGAWR 84745473/5 4800 FGAWR 84745477/9 5200 FGAWR 84745481/3 5600 FGAWR 84745485/7 6000 FGAWR 84745489/91 In general, diesel crew cab sb 4wd are 5600 FGAWR and gas crew cab sb 4wd are 4800 FGAWR without heavy front or snow plow options. If you have any other models, I can look up when I have time. #iworkforGM
