Welcome from across the way a bit. I lived in San Antonio for 11 years before I moved here (just north of Houston). There is a lot to learn for sure. I think Tiercel has a great post. But don't let the maintenance side overwhelm you. Take a trip or two close to home. Learn the basics (parking, hooking up, dumping (always a subject of interest), tear down, etc. I say close to home because you might find you forget something you really need. And it's also kinda close and in your comfort zone.
I also recommend you bring a notepad and pen/pencil (or the electronic equivalent of it). This way you can write down things you forgot, things you brought but don't really need, things that didn't work (or work quite right), and things that did work (that make you feel good).
And finally, like Gary said, ask questions here. there is a lot of experience on this forum. Someone will have your answer.
So, welcome to the forum, and hope to see you down the road.
