I hope I don't start a flame war here...but.....
I have an '06 LBZ that I bought for towing my 10Klb RV, I wouldn't have gone oil burner if not for that. I got lucky in that the LBZ has not been plagued with massive repairs like so many other models. It has been great. Fuel expense, well, you have to pay to get that kind of performance.
Having said that I'm having trouble understanding the appeal of this small diesel in a 1/2T. You are signing up for all the vagaries of new diesels, low lubrosity issues, fuel contamination, fuel filters, under designed fuel pumps, DEF, etc but not getting any advantages. If you want towing capability you've got a good old fashioned gasser that the industry and the EPA seems to have a handle on designing/regulating.
I hope my comment does not get me banned from the site. I do love my LBZ.
I would like to see the 2020 separated from the (Duramax Sixth Generation: 2017+ (L5P)
Maybe a (Duramax Seventh Generation: 2020+ (L5P)
I agree the 2020's need their own page/forum.
I hate to nitpick, but I wish the “Generation” would be dropped from the forums titles or fix it to corroborate the actual generation of the engine. It’s a fact that the L5P is the fifth generation of the Duramax, hence the 5 in the L5P. It’s confusing when it says it’s the sixth generation on the forum. It would be much easier and clearer to understand if it simply said “L5P- 2017-19” and “L5P - 2020+”I've brought this topic up for Admin discussion ...
We'll keep you posted on any changes.
I'll add this to the discussion as well.I hate to nitpick, but I wish the “Generation” would be dropped from the forums titles or fix it to corroborate the actual generation of the engine.

According to General Motors, the L5P is the fifth generation, seems like they would know lol. They have LLY and LBZ as same generation.LB7, LLY, LBZ, LMM, LML, L5P
The 20+ has a bunch of external engine changes as outlined in the banks video. Engine cooling system changes are at least part of the reason they could increase tow ratings.
So much is changed for the 2020+ powertrain that many discussions about it do not apply to the 17 thru 19 trucks.
There was a guy on You tube that previewed the 2021 interior update for the full size SUV's. IE Suburban/Tahoe and GMC's. He said on the vid that the trucks won't see the upgrade for another year or two but who knows for sure.FYI, rumor has it gm is upgrading the interiors for 2021, drastically supposedly, to compete with the dodge interior from one article I read.
I wonder if this would help a littleBy far the worst is the shake / wobble in the steering wheel. I've been to the dealer 4 times now, and after all the GM fixes, TSB, and balancing the tires 6 times, the problem is better, but still not fixed by a long shot. GM finally told the dealer there is no actual fix and they would not pay for anymore warranty work for the problem.
I drove four others on the lot, and they all have the problem. Some way worse than others.
