Advice
I worked for Furrion in specific, which is now owned by Lippert. If I have any advice... you've probably heard this before, but ask questions whenever you want to. Sure, you can Google it, and sometimes that is OK, but oftentimes questions are a great way to build a relationship, update coworkers on your project, and learn more about everything.
Next: don't assume your coworkers know everything, either. It is okay to experiment within reason and test things.
Also, as an intern, you have a unique perspective on the company. Likely, you will have something valuable to say, so don't be afraid to speak up on how a process could be improved if the opportunity comes your way.
