Thought I'd post this to alert any other drivers of the possibility.

We have just purchased another Hyundai Terracan and I am over the moon with it. It does briliantly (much better than all the others I tried although teh Hyundai Sante Fe was excellent too but visibility was poor for me (6'4")).

We were towing back from France last week and it is rock solid even at the higher speed permissble in France.

However, when we got back to England I noticed that it was suddenly bahaving badly. I thought something must have moved in the caravan. However, it was all down to the lorry that we were following. It was a car transporter and the air flow coming off of it was causing turbulence that felt similar to snaking and I'm sure could have caused one. I recognised the feeling as I am a paraglider pilot and I know what rotor feels like; particulary from another air craft and thsi was very similar.

So I overtook the truck and everything was perfect. in fact as soon as I was alongside the truck it was perfect.

Just thought some of you may be interested to know that wind turbulence can cause your unit to wobble.

Yes, we have experienced the same. It can be quite scary until you realise what it is.

a car transporter is supposed to be the worst for starting a snake.a coach passed us the other day and i was convinced it was going to pull us to it.

Yes, and coaches can travel at 70 which makes it worse.

But if you follow a coach or flat sided truck you can reduce your fuel consumption by about 20% due to the "draft" sucking you along behind.

If you're close enough for it to benefit your fuel consumption you are probably too close for comfort. And if it's a coach doing 70 you're speeding.

This is what I was thinking.  I try to maintain a distance of at least 3 juggernauts length from the lorry ahead.  If that lorry is doing less than 60 mph, it allows room for any passing lorry to go into the gap (if he should decide to) and, as such lorry will be drawing away from me, only a few seconds elapse before I am back to a good clearance.
