Why are there no curtainsider trailers in N.America?

Saw a curtainsider myself yesterday, it was a 2 axle rigid on local work. Didn’t get a shot of it, it came past too quick. Well anyway, over here any curtainsider is treated the same as a flat for load restraint rules, at least by the septics.

From what I’ve seen of European curtainsiders, there is often a hinged kickplate that seems to be there to keep stuff from sliding out the sides. US curtainsiders never have these.

Alexx,
That is probably a tilt trailer you are talking about rather than a curtainsider,you don’t really want to be running a tilt,nobody likes them because they take along time to strip down to look like a flat.
Check out www.dennisontrailers.com to see a good selection of UK trailers.

another reason for the low number of curtain siders could be that land over here is for the most part cheaper. therefore it is easier to obtain a larger lot making it more convienient to have dock doors
