I notice some trucks roof slide under the back window and the Rams slide over the top. Wouldn’t there be less wind resistance with the glass sliding underneath?

there's a windscreen that comes up at the very front so I don't think it matters on which side the roof went, either way it's in the "bubble" so to speak. Kind of like how a housefly can fly around a car while you're doing 80 mph on the highway, it's in the "bubble" so it doesn't matter where it is.

Absolutely - however designing the interior/pano assembly around glass aerodynamics on a truck is a futile exercise. Though, would help with wind noise... which the windscreen does help a bit with.

Also if you notice, the glass opens to the 'best' wind resistance/sound position, and then can be opened further but it will cause some serious wind noise at highway speeds despite the windscreen... so someone was thinking a bit anyway when they designed it to stop early

Hmmm, now I'm curious why ram chose to go above not under.
Not sure, but I can say that I like my Ram Pano much more than my F-150. The seals on the F-150 get dirty and super tacky. This causes the roof glasses to bind, resulting in a rattle that cannot be eliminated. Numerous owners have had their roofs replaced, only to have the rattle return within a month or two. I literally had to vent my F-150 pano just to keep it from rattling daily.

Having had both, there is no wind noise reduction between the two styles. The F-150 has more buffeting with the roof open and the rear window closed. Near zero buffeting on my Ram with the roof open and rear window closed. I really enjoyed this during our sunny sub-zero days last week. Heat on, steering wheel heat on, seat heat on, sunroof open, sun shining in, -9 degree's...felt like a summer day inside the truck...and I'm not joking. Cruised down I-94 at 75mph, roof open, super comfortable.

If it slid under the rear panel, it might or might not reduce wind noise but would reduce headroom...

That just reminded me - don't enter a parking garage, even in Entry/Exit, with the sunroof open!

I think the sharkfin sits higher than the window... I can't check the truck at the moment though.

The roof uses the same mechanism the coupes with sunroofs use (no way to go under). My F150 went under and there is a significant loss of headroom in the rear. Both styles have the same wind noise/buffeting which isn't bad ati.

With my down jacket, winter hat, and heated gloves :eek:) Just joking. I do the same but probably not that cold.

I'd happily pay for a new shark fin before the sunroof glass - and whatever else bent...
