Gunny,
I'm going to offer you some unsolicited advice.
If I were doing this, before I traveled more than a few miles, I would stop somewhere they were used to working on trailers and have the wheels pulled and get all the wheel bearings inspected and either re-packed or replaced, as needed. They would also adjust the brakes properly when they reinstalled the wheels. Hopefully, you won't need new brake shoes, but it will certainly be cheaper to replace the shoes in CA than to have to replace the shoes AND the wheel drums when you get it home.
Finally, the tires need to be checked for age, signs of dry rot or other problems, etc. A blown trailer tire can cause a lot of damage to the trailer when it lets go. Far cheaper to buy and install new tires in CA before you start.
A lot of trailer tires are really cheap, made in China junk. Over in the mainstream RV forums, they call them "china bombs" because of how often they blow up. Even some of the well known tire brands have their trailer tires built in chinese factories. Maxxis 8008's seem to be one of the best trailer tires currently available, and they would be my current choice for a trailer.
Good luck with it!
