Not crazy at all, my first tour was from Anchorage, Alaska to Panama City, Panama
Before I left for Alaska I had never ridden longer than a day, lol
As for your bike, for touring I wouldn't get anything that has carbon components, since they really aren't designed to hold loads
I didn't tour on a touring bike, but rather on a cyclocross bike (Cannondale Cyclocross Disc)
The deafult gearing isn't good for really steep climbs, but the stretch you plan on biking doesn't have any
Basically for the route your planning though, nearly any bicycle would do
I would disagree with the last poster about changing gearing, my cyclocross bicycle had typical road gearing setups and only two chainrings up front (no granny gear) and I was cruising along just fine
