At the moment, the R/T's with the Road/Track package are very hard to come by. I assume that DC will be pumping more of them out as time goes by. It's frustrating because I really want to drive one before I commit to buying it.
Same boat. When I ordered mine 8/11, the dealer had never seen one with the RTPG package. I read (a LOT), every magazine and online test drive I could find, all seemed to point to positives getting the package. Financially, it really is a no brainer, if you already want the Convenience Group II, which is included. The strongest personal reason not to is if you don't prefer the seats, as they have a lot more side bolster area. One article I read said avoid it if you have bumpy roads.
I've since driven both, I made the right decision ordering the RTPG. It's not huge in any one factor, but all the combined upgrades are worth it as a package. In SE Michigan, we have very crappy roads. I drove on some intentionally, and coming from an '02 Durango with a very truck like ride, the Charger even with the "sport tuned" suspension, soaked it all up nicely. And, I prefer the more connected feel of the steering and suspension. It's not a "sports car" ride, but a nice "sporty family car" ride still, to the extent you probably won't feel beat up after a long drive.
Black pockets on the wheels? Don't care really. Tighter steering? Oh yeah! Tighter suspension with load leveling shocks? Yes! 10 more horses? Whatever. Tuned exhaust? To each his own, but why not? I don't like "loud", but the little bit of added rumble is pleasing. Seats? Big thumbs up, they're still okay to get in and out of (5'11"' 200lbs), and hold you right there.
Conv. Group II stuff? Gotta have it! Not so advertised, the top speed is raised from 129 to 143 or so. Due to swapping out the crappy P225 60R18 Conti tires for crappy Michelin P235 55R18 (MXM4?) rubber. So, a little wider and a little lower profile.
IMHO, the RTPG package should have just been the standard R/T equipment, but I dont mind at all having choices! And, when it comes to resale, I'm sure one with RTPG will sell over one without.
Yes, it's basically the Daytona without the paint and stickers. I've heard the exhaust between the two sounds a little different from some people, I have not been able to verify that the Daytona has a unique exhaust system.
