We seem to have these on all our wagons now do you think they save on fuel ? You don’t see many firms apart from supermarkets using them.
nah they are actually poop scoops for when you get caught short in layby’s !! 
Sure their not pull offs to scoop up the PR bull that some uni reject came up with [emoji6]?

Do they come in chrome?? 
We have them on the ones we drive but not every unit. As we don’t have the same units every night I’ve got to drive wagons bought at the same time with the sme mileage on and I’ve seen no noticeable difference between the trucks with and the trucks without. If there is over a year I don’t know but I think that there has been a good marketing bollox job done by their creators.

Yeah thinking about they do look like it

I’m sure it could be arranged.
At this very moment on some sunny beach in the Carribean, a group of snake oil salesmen are quaffing cocktails and their every wish being attended to by dusty hand maidens, phwoarr 
Among the happy throng is one chap who managed to sell a batch of pratnavs to gullible lorry users with more budget than sense, another one who sold them telematics, another one who sold them trackers, etc etc, and one bloke on the end who’s got them all in stitches, he managed to sell them thousands of self adhesive plastic triangle wedgies and convinced them that attaching these things to the wind deflectors would not only make their vehicles look stupid but they’d actually save fuel too…
According to airtab.com they save on average 4% of your fuel

Frigin no way they things save 4% on fuel. I’d bet my mortgage on it. 4% is massive in terms of fuel saving.

4% my rusty ringpiece.
I have to laugh at all these daft stick on things, Stobart’s flappy mats and all the ‘driver training’ junk (don’t accelerate, don’t brake, let it roll everywhere) that goes on when underpowered units are cutting around fully loaded with 15 and a half foot trailers on and either miniscule or non-existent air deflectors on.
A.
Vortex generators I think thats the name of them, we have them on top of our trailers we also have side skirts all in the name of fuel economy.
Over the life of the vehicle they are supposed to be a good investment, however those responsible for having the fleet fitted out didn’t bank on club plant pot wrecking all the side skirts and the thousands spent on repairs far outweighed the savings, we could have saved far more with a tyre pressure monitoring system which is now available, stupid is as stupid does.
Think Morrissons have them on every truck too BB
looking at the blurb, it would appear that they also keep your machine cleaner, improve visibility through your mirrors and stabilise the vehicle in cross winds … i wonder what the boys on the forth road bridge would say if you rolled up on a wild autumnal day and pointed to your new miracle devices.
Only thing is…the snake oil salesman forgot to tell his customers to fit them the other way round.

Car Bibles is a good source of info IMHO.
And to repeat the killer question:
If these devices are so good why don`t Volvo Scania Daf Renault Iveco fit them as standard?
A prize of up to £10 million to best answer.
We have two units fitted with them, and they save so much fuel that they haven’t bothered fitting anymore
wrighty:

Just like teardrop trailers then? They were the thing to have for a while but they seem to have rapidly diminished in numbers these days. Maybe because they didn’t really save all that fuel or possibly because they are totally impractical with a smaller rear door and higher roof (which can mean diverting round low bridges)

Jesus wept, every day you read or hear something that has you thinking ‘thats it i’ve heard the lot’, without fail another howler comes along that trumps the previous.
Who the hell believed that BS. , someone another someone trusted with a budget too.
Apparently the next wave of new containers are going to be teardrop shaped-please don’t rock the boat!
They are ridiculously stupid.
