Go there all the time, plenty of room for big trailers once you get there. The fun part is the drive in. You make a pretty good climb on a narrow road. We try to have a solo vehicle run ahead of the group to let us, or the on-coming traffic know we are coming thru. There are a few places to gt two big trailers past each other, but not many.
Not trying to scare you away, just letting you know in advance. The ridding is endless and trails are good. Rangers do check for proper equipment, license, and decibel level on pipes.
