Like you, i have just recently acquired a T6 Combi. The first things i have done is sound deadening, thermal insulation. It does make a difference, especially if you plan to stay in it. For now, I'm going to leave the back seats in. So I'm going to fit either a Kombi bed or VANking bed system. After that, I'm just going to get out there and then decide what i need on my Camping trips. And write it down. As Fish mentioned above, why spend £1000s on a full conversion if you don't need it. I'm starting with the basics, will then add what i need as i go on.
