Has anyone removed the fridge and sink/hob unit from their van? I'm considering getting rid, and having taken a moment to look at the connections this afternoon, I'm a little unsure of how it's put together

From what I can see, some of the gas pipes run down into the floor and others out the back of the cupboard unit and into the body of the van.
So before I attack my baby by taking up the floor and ripping out the units I thought I'd ask if any of you have done this, and if so is it straightforward?
