If you don't want to go in debt for a trailer - rent a Uhaul and then turn it in when you land.
A 13 year old vehicle with 98k miles - lets see - you didn't say where you live now but if it is/was in the snowy part of the country there is probably a lot of rust under your vehicle.
NO - I'm not saying get a new vehicle to tow. Just really check out the underside of your vehicle for rust, you may be amazed at how rusty it is, as most people never look under their vehicle.
If you had a 3 year old vehicle with 98K on it that would be a different story. I've seen frames crack and break making vehicles undriveable.
My advice is to really get under the vehicle and check it out. Jack it up and use jack stands and really take a good look. If anything is iffy get it fixed. Unless you know nothing about vehicles
I would recommend YOU look under it, as a service tech ISN"T going to be driving 1600 miles with his prized possesion in tow, right? Not to mention all the other stuff you will be taking.
Better safe than sorry, right? Check the trailer hitch real well, that area of the vehicle seems to have a lot of salt and road junk thrown at it. Don't forget to check that air pressure in your spare tire too.
If the trailer hich bolts are real rusty - replace them. If the hitch fell off, the chains on the trailer will do nothing to keep it from rolling down the road if it broke loose.
I'm not trying to scare you - but I would hate to see any guy mess up his bike (or other property) because no one reminded him to take an ounce of prevention BEFORE he left to go
cross-country in a 13 year old vehicle.
If you have never used a trailer, I have a coulpe of tips.
If possible (and you don't have a stand mounted to the floor) try to set your Busa at the front of the trailer. EVERYTHING moves forward in a move like the one your going to do.
If the Busa is in the front it can't move anymore forward. It would be best if the trailer has tie-downs in the floor. Believe me EVERYTHING gets bounced, rattled, and shaken in a move. You need to
really tie it down well. Some roads in America really suck and you have no choice but to drive over them!
90% of trailers (including Uhauls) are designed to be driven at 55mph. Many people don't care and drive 70-80mph. I wouldn"t do that in your 13 year old vehicle.
It wastes Gasoline as your mileage will aready go down just by trailering. driving at 70+ you will use even more. If your vehicle is going to break it will break easier and sooner at higher speeds.
Remember everything will get shaken etc. more the faster you go. You don't want your Busa moving around, right?
You may want mirror extenders - if you haven't trailered before it can be helpful for a rookie. You don't want to pull out to change lanes or whatever and get hit because you
didn't see someone coming. Even if it is not illegal it might be worth it - I think you can rent those too. I still use mine when I trailer and I've gone cross-country a few times.
I hope this helps. You can PM me if have any questions. If we live close (AZ is about 1600 miles for me too) Maybe I could help more - I don't know. Good luck.
