We've all been newbies, and most of us are still figuring things out. Were it not for the kindness of strangers........
Get out there in your rig and work with it, perhaps in a friendly, nearby campground where experienced campers can answer questions.
Maybe go to a rally. There's a good one coming up in a couple of weeks in North Carolina. Alumalina. Check it out on the rally page.
There are several nice Streamers in RI that might read this and invite you over for a weekend of learn-as-you-go.
Good luck and have fun!
