Congrats on the 2015 R-Pod 178! Lots of good times are ahead for you & the family. Towing is pretty easy as the camper will follow but watch the tail when turning sharp or backing up. Go to a big empty lot and practice parking & backing up.
As for shopping - you might be able to wait to get some items depending upon your camping style and the campgrounds you are visiting. Most likey you will want to upgrade the fresh water & sewer hoses. Most WalMarts have a small RV section close to the auto section.

Consider going to the Oregon Roundup, a FROG event that is attended by many, many RPod owners. You will meet lots of nice folks and learn a lot about your RPod.
Welcome from Minnesota. Our first ever camping trip with an RV was at the closest campground to home. We ended up making a few trips home to get things. Just don't forget the most important thing to camping; FUN
