Welcome to the forum. I'm sure you'll find a wealth of information available to help you learn about RVing in general and about your "new to you" Sprinter fifth wheel. Being a "novice" to the trailering world, you didn't say what you're planning to use as a tow vehicle for your Sprinter. That's a pretty good sized fifth wheel with a relatively heavy pin weight, so make sure your truck is "up to the task" of towing something that heavy.
Again, welcome to the forum, we're happy to have you join us.
