Welcome to rv.net. Being a class C owner myself I think that you made a wise choice. As far as driving a class C it does take some getting used to. Just remember that you have 26-30 feet of vehicle behind you versus 15 to 20 feet of your current vehicle. Just take the turns wide and have a spotter when you back up. As for maintenance of your class C it is not much different than a truck. Obtain a good pre-trip check list online or compile your own. The 2 things that are most important to me are checking the air pressure in your tires and your fluid levels. Do that often, change your oil at least once a year or more and you should be good. Have fun on your upcoming adventures.
