I speed is #1 priority - Fly
Don't want to risk tire issues (maypops) - Fly
If speed limits are too low for you - Fly
If mpg is important - Fly
If you don't like to do your own maintenance - Fly

Heck, just sell your rig and fly. Don't have to worry about campground/rv park sites being adequate. Don't have to worry about finding fuel stop locations. Don't have to worry about walmarts allowing you to "set up". Don't have to worry about tire issues.
That's what we did. It's not as much fun for you get there much quicker and for less $$$. :(
