Well BB, first you have to get your tag, they are going to sell out fast.
As far as the RR mountains, like was said, you will see lots of hunters, but that pretty much is true for most of the Northern area. The Rafts can be fun to hunt if you figure out where the other hunters will push the deer. It has a lot of private lands both on top and along the outer edges, so there are just a few main ways in. Wheelers will be on most of the avaliable roads/trails from day 1. But mid week, it will peter down. By then the bucks will be buried in the deep thick stuff, but can still be spoted.
The Grouse Mountains to the west are similar. Still, if you put in the effort, you can find your buck. Good luck on the tag!
