I'm not seeing some of this, and I'm the OP.
I didn't say anything about the suspension being the same 2005 vs 2020. The 2020 has the "miracle" $1200 apiece magnetic shocks and the ride is disappointing at best - nothing like the used 2020 I drove before buying this one. The 2005 has all original suspension and the leveling compressor still works. Ride is as good or better than the 2020.
I'll just add ride better means something different to everyone. it's very personal.
some guys want their suv to be responsive and and flat in corners and don't mine firm over bumps. I am the opposite, I want to feel like I'm riding in a 70s caddy. but floaty cloud. I have the mag ride on my 2011 denali and it's to stiff for my taste around town too. I've seen it's benefit in a quick avoid an accident at 50 ish, and I've seen how it handles towing with a lot of tongue weight and it can get control of a big bump very quickly. but it's all in the tuning, and I'd love to soften the ride around town.
I leave all that hard spring rate and roll bar for car stuff.
to others it can mean you feel every peble or line in the road. a lot of that is tire type and lack of side wall in these 20in and bigger tires. mine happened to come with the smaller 18s instead of the standard 20s and whole I don't really like the base look. I do appreciate the lack of road noise and harshness over washboard surface.
so when you say rode better. that's a very loaded question. some guys want to sail their 6k lbs suv into that clover leaf at 80mph workout a thought. others want to ride on a cloud.
