Dave, I paused and rewound the clip (from the link you posted) a few times to try and see wtf he was up to.
It looks as though he has a pile of earth (with barrel, slates, etc) in some sort of a timber "sandpit" behind his market stall. I doubt this is as easily mobile as his insulated-looking trailer...
I have to admit that I am confused by the various Spinks, and the EU PGI status.
http://www.scotland.gov.uk/News/Releases/2004/03/5295Where we learn that RR Spink are targeting the market of "multiple retailers" (ie supermarkets?).
Although from
http://thescotsman.scotsman.com/magazin ... 1312422006 we learn that they also sell wholesale to the "world's finest shops".
They have Royal Warrents and a long history

But it seems that Iain R Spink in the video (despite his logo on the trailer being blurred for broadcast at the start of the clip) is another different, new, independent, and very small business.
On
http://www.arbroathsmokie.net he reveals that he is part of the RR Spink family, but doing his own thing. Mobile smoking at "events". All over Scotland (blowing the PGI status!)
Isn't that Jamie sitting on the timber sandpit?
http://www.bbc.co.uk/food/recipes/mostof_smokies.shtml And then we have these guys
http://arbroath-smokie.co.uk/catalog/smokie.php using "any hardwood" in brick 'barrels'...
Shouldn't the "traditional method" be closely defined for PGI purposes?
But for sure its dense smoke, hot smoke, and for up to an hour and a half.
I think that Iain R Spink's protestation that the Smokie is 'mildly' smoked is probably about distinguishing his product (smoked less than 40 minutes) from the more heavily smoked products that others produce.
