We're doing a longer tow of a '67 Overlander but here's the rough checklist.
1. Replace the tires. This is relatively easy (though not inexpensive). I would throw in a pair of ramps to make the change easier. Of course, don't forget your lug wrench. If you want a picture of my ramps, check my Yahoo360 blog. It didn't take long to cobble them together.
2. You might be able to tow it 50 miles without checking the bearings, but if you have the time and inclination, repacking the bearings onsite is an option. If you are pulling the tires, why not pop off the hubs and take a look. Even if you have some bearing wear, it's still a chance to get fresh grease in.
3. There's not much you can do about the axles, but the experts tell me that a true catastrophic failure is rare.
4. Bring your own lights. You can pick up a set of temporary, magnetic trailer lights at a place like Tractor Supply. This gives you the chance to test the lights with the TV. Sure, the lights on the trailer may work, and they may not. I have problems in the running lights for my Overlander that are still eluding me. My solution... replace all of the wiring when the shell is off... but that's not something you can do in someone else's driveway.
5. Bring the standard emergency stuff... just in case. Go slow. Make sure the TV has trailer mirrors. (Vision is important). As noted frequently herein, "stow for sea." Stop after you go a mile or so and do a walk around.
6. Ride with pride... you're one of us now.
