New Travel Trailer
Congrats on the new travel trailer. Big boys and big boy toys.
Spend some time going over and reading every manual. If you didn't receive these, you may be able to obtain them from the manufacturer. Read them!
Spend your first weekend in the driveway. Learn the systems, what does what, and how to enjoy what you've purchased. Then the next trip to a local State Park which may or may not have services. Learn how to exist without inconvenience without water, shore power, TV, cable, sewer, etc.
Also during the week, find a church parking lot that is empty. Practice backing the trailer into a parking space. After a few times, you'll look like a pro at the campgrounds.
