Advice requested : overlanding

Hi all, I am brand new to camping in general but the idea of having a tent on my car really interests me. I have a 2013 Tiguan 2.0T SE With a moonroof. I have 2 questions I would love the expertise of this community to help me out with

1. Will my Tiguan be able to support the weight of an overland tent with people sleeping in it with a moonroof?

2. What will my car be able to handle? Any Advice on terrain to avoid? (I’m in SoCal)
