The TAT is a great adventure, if you have time, plan side trips off of it as well. Many things to see all over. Dont go to early, snow in the high country can kick ones ass. Might want to read some of the Vintage Ride we are doing. However, always a way around the snow, but high mountains are my favorite part of riding all the parts of Colorado. Riding solo, several have done it. I would take a SPOT tracker if I were going alone, just in case. Shit happens to the best of us. Good Luck.
