My local dealer gave me a 2020 Laramie Longhorn for an hour+ tonight. I only put 30 miles or so on it, but here's my impressions if anyone cares.
Interior is louder than my Honda or the F150 platinums I've driven. Sound meter (non-calibrated microphone) shows 62-64 db in the Ford and Honda and was 65-69 in the Ram (same roads, same speeds, etc) I could hear the wind noise (open door) so many complain about (passenger rear door noise), but believe I can correct that based on what others here have done. It was a little better with the sun shade closed, but not much.
Seats are comfortable and have great adjustability. The driver's left seat base bolster was bothering me a bit, but likely due to it being stiff (not broken in) Seat heaters, steering wheel heater, climate control all seemed to work very well.
Access into the truck front and rear seating is awesome. Best in class for sure.
Visibility is good, but not great. Head rests get in the way (front and rear seat) when looking over your shoulder. Rears can be folded down.
Sunroof and shade are great. Roof tilted is noisier than the ford or honda. I didn't try it opened.
HK stereo isn't nearly what I had expected. Sound quality (Sirius and USB source of lossless media) was meh....I adjusted the EQ etc and it just never was great. Honda is better...Ford is about the same.
Plenty of power (5.7 E-Torque), but not "wow" power. It's a truck...not a race car. Averaged about 18 on my short drive which included hills, city streets, neighborhoods and highway at 65 MPH.
Transmission shifts well. This truck only had 11 miles on it so I'd guess the TCU hasn't had enough time to learn and smooth out the shifts. Some downshifts at slow speeds were abrupt, but it never felt lazy accelerating from slow speeds.
The truck bumped forwards several times when sitting at a light (engine off due to stop) when I lifted my foot off the brake pedal...not all the way off...just enough to let the truck roll a bit. The engine started and the truck jumped forward a bit. Surprised me. Not dangerous, but unexpected.
Headlights are great! Better than Ford or Honda.
The myriad of controls and adjustment on the 12.4 Uconnect are staggering. I found it easy to navigate and found what I was looking for without much trouble.
Wireless phone charger wouldn't charge consistently with my Note 10+ and Samsung rugged case. I removed the case and it worked fine.
Took 4 tries to pair my phone to the truck. My phone didn't see the uconnect the first 3 holding it over the console. I held it near the charger on the 4th try and it worked.
Suspension was plush and silent. I did hear a rattle from the passenger rear a couple times on stutter bumps. Sounded like it was coming from outside the cabin.
Overall a pretty nice truck. Best interior, not the best in other ways, but what is?
