Hi Ron,
i bought my ST in Nashville and rode it home to Portland, averaging about 500 miles a day. You might find some useful info on my blog for the trip at

Some general tips:
* plan for a shorter ride on day one. There are all kinds of things that can slow you down and you don't want to have to push yourself on a new ride.
* use the google "near" search feature to find hotels. "hotels near Dallas" find some ahead of time and get them in your GPS so you don't spend valuable road time looking for a place to stay. You'll be safer if you have options. Don't make a hotel reservation until you're a couple of hours away.
* you'll be able to ride farther and be more alert if you stop and stretch your legs and get the blood flowing in your butt every 100 miles or so. It just takes a few minutes.
* don't ride late at night. That's when the drunks are out and you'll be tired. Instead, leave early in the morning and get in a hundred miles before breakfast.
* don't forget basics like ear plugs, waterproof boots and rain gear. I ride with three pairs of gloves, mesh for warm weather, leather for mild and heated for cold weather. Get a tank bag if you don't have one.
* it's common for riders to say avoid Interstates but in many ways they are safer than back roads. You can make better time too.
