Am I not right, Hils, that that is 21 foot shipping length? A mate of mine in Canada has a thing that is I think 30 feet internal length, 9 feet wide (although no wind-outs), and near the 6,000 lb towing limit of the specially reinforced towing hitch on his huge 4-wheel drive. If he used it on the road over here he'd fill several pages of an official police notebook!

For quite a long time in the UK the maximum UK length was 21 feet excluding drawbar and hitch and 7 feet width, and EU legal vans exceeded that by a little bit in both directions. Now the UK is 7 metres and 2.55 metres.   

While I am on here, I'm having fun with my bulldog coming out of the slipper plate. Anyone know anything about packing the slipper plate up or getting an offset toothed wheel to enable an in-between height setting on the towcar?
