Go South to San Antonio to Travelers World RV resort for a weekend to try everything out and get accustomed to the workings, they have full hookups so you can practice dumping, they have pull-troughs and back ups, best spots are along Av "B" backups along the wall on the golf course nice and quiet.
Before you start travelling go to an empty parking lot and practice going in reverse as if you are going to park the rig in a backup situation, you and the girlfriend need to do this so that you both are comfortable, purchase some walky-talky's to communicate instead of shouting, always make wide turns to the right and you are allowed to go on the opposite side to make a turn, always wide turn both sides.
Most important purchase an air compressor and slinky hose with a tire pressure gage, it is very important that tires have the correct inflation pressure, specially the trailer unit, also make a list of what you have to connect and disconnect, and in what order and before moving do a walk around to make sure everything is as it should be.

This is close to Austin, and if you forgot or need something from home you are close enough to run and get it, if not there is a Camping World at:
3891 Interstate 35 Frontage road, New Braunfels, TX 78130 Tel 1-888-426-4511
Always dump black tank first and then grey and have enough water in black to flush al solids out, do not leave black tank valve open while in camp, you want as much liquid in to dump otherwise you will have the dreaded poop pyramid.
Hope it helps, we all started not knowing what to do and very excited to have a new RV, enjoy and welcome, any further questions we will be happy to assist if we can.
