Welcome to the forum. We also have a Hemisphere.
I guaranty you that that you will have a bunch of bugs to get out of it. If you can plug it in and 'camp' in it at home it is easier to kill the bugs at home instead of at a campground. Run it through a workout.
Get a lug wrench that fits the lug nuts and make sure it works....Standard 4/way may have to thick of a 'wall' to fit on the wheel.
Get out the grease gun and a couple of tubes of grease and grease your hubs at the grease Zerts. The factory does not 'fill them up', only a passing amount of grease. There are instructions on this forum on what to do.
