@silver billet post is mostly on point.
Do you own or have driven extensively a Cummins HO/Aisin?
I have.
The Cummins doesn't need all those gears - at most an 8 speed (ZF would be nice) but the Aisin is by no means a "joke" (current small batch K1 snap ring issue notwithstanding). My truck shifts smooth and pulls hard. The modern Gm built Allison is a joke and stands up to tunes no better than any others, the new 10-speeds in the Ford and Gm are a joke with recalls and constant gear hunting. They shift like a Jack F'ng Russell Terrier on speedballs. If Ram were to use an Allison it would no doubt be a real Allison 2000, not that GM built POS A1000. If the rumors hold true, we'll see an 8 or 9 speed ZF in 2025, possibly a mid year 24 release.
Who's "everyone" that says their Aisin shifts poorly? You're regurgitating old internet gossip from pre-19 truck owners and others like yourself that don't' actually own one. The current TCM code on the Aisin shifts smooth.
As posted, I just had a 1500 loaner for a week. The doors felt tinny and weak compared to my "ancient' 4th gen cab. Rattles when closed.
The frame issue is non-existent, again you're just regurgitating internet rumor mill BS. That truck (and some others) was grossly overloaded. It also broke in Baja. Most of them were also welded on improperly. There's plenty of F-xxx trucks and others with broken backs from excess overloading.
"Laughing stock?" Hardly. What are all the hotshots driving?
