Yes Paul, and the operative word in what I wrote was "If", so thank you for clarifying matters, but no "pessimistic view of the StuG and its owner" was made nor implied, I trust you'll concede.
As an onlooker to yet another apparent TM bashing thread (StuGs & their maltreatment seems to be the soup du jour at present, it appears), I was simply stating a possible reason (in my own admitted ill-informed opinion) for the reported reluctance of the TM to continue with hosting an externally owned vehicle. It appears I was wrong, which is absolutely fine by me - it's a poor day that goes by when you can't say you've learned something...
