That is exactly why an RV ownership is so convenient. You can go to any event, anywhere, for any reason and have your OWN bedroom with you!
We used our camper for "events" also, many times over the years. A couple years ago, we took the camper and stayed 3 nights at a KOA, just so my wife could attend a Barry Manilow concert. It worked out great! And then 2 months later, another campground so we could attend a Kenny Rogers concert!
When my daughter graduated her advanced training in the Navy, we took the camper to Charleston SC just so we could be there for the event.
Yes... you've just discovered new uses for the camper! Enjoy and be proud of your son!
