I gave a huge amount of thought to this subject recently. In the end, I decided that trailering was best, expecially because I already have a $400 lawn-mower trailer that, with a little work, oughta do just fine. I've pulled a boat many thousands of miles down good roads and bad, and everything from a 12' U-Haul to a '73 Buick halfway across the country. While I've never had to tow anything really large, such as a big RV, I would not hesitate to do so. Towing becomes easy once you've got the first couple hundred miles down, and once you've learned the skill and bought the hitch it becomes incredibly handy.
One note- the shorter the trailer, the harder it is to back. With a small utility trailer, it's better not to even try in most circumstances.
One thing that made my decision easier is that my primary truck is a 1995 K-3500, whose bed sits very, very high. I've tried to ramp lawnmowers into high beds before, and **** near got killed doing it once. Note that if your truck is a 4x4, then very likely you will need a much longer ramp than you would for a two-wheel-drive, especially if you don't have a high spot at each end to load from.
If your truck is rated for 450 or more pounds of tongue weight, you would probably be pleasantly surprised at how easily one of the receiver-hitch carriers handles a Burgman 400. (After all, weight is weight. If the suspension and carrier are designed to take it, then they will. It just takes a little faith, is all.) The main reason I didn't buy such a carrier is becasue it looked to me as if I could not ride onto it or use engine power to ease the bike up onto it, and 400 pounds of 400 is too much for such a steep angle, in my book.
Hope something works out for you! And, I'm interested in better ideas, too!
