Howdy and welcome to Airforums.com to Rust and Mrs. T, two new Canadian members!
You're already seeing how much good information you are going to get on here, from MaryD and YankeeDoodle!
As for space, you have a nice big new trailer, Rust. As the old saying goes, take half the clothing and twice the money you thought you would need, and things should turn out just about right.
You'll have tons of fun finding out about all the nooks and crannies that you'll be tempted to fill, but ask yourself if you really need to before you do it.
