Things I learned on our first trailer camping trip:
1. I still suck at backing it up.
2. We need a proper awning.
3. There is a major issue with the 12-volt system and I know shit all about electrical stuff so it's probably gonna cost money to fix.
Overall, though, pretty good and generally more comfortable than tenting. Plus, it's way easier to pick up and go, since I can keep most of our stuff in the trailer at all times and have much less to pack as a result.
