Nicely done Sir! I towed a loaded trailer to Banja Luka (Bosnia) in one hit, a few years back. 1520km ish, so just shy of your standard!
However, there was only two of us to share the driving.....
I found a post card I sent to the missus from there the other day (they keep all sorts of rubbish, don't they?!), it made me laugh. I ought to scan it and post it up!
