Rapido V68
I am looking at B2B for my Rapido V68, however one of the questions I need to answer is where is the earthing point on my van. How do I find out? Attached is a very crude diagram. I want to put a Victron B2B in this diagram as well as replace two AGM's with a single 100ah Fogstar that I am thinking of getting.

It's probably a case of chasing the B- (Masse) terminal wires from the distribution module to see where they connect to the bodywork
 
As dunnah01 says. However if you can't do that, any solid connection to the bodywork will be OK. I think the negative terminal of the B2B doesn't take a very high current, even though the two positive terminals obviously take the full output spec current. It just needs a negative connection so that the internal electronics works OK, the main negative return current is through the chassis and the negative battery terminals.
 
Just attach the neg wire to the vehicle battery earth connection next to that battery.
You should then have the best earth possible.
