Not owned a caravan for long but mine has atc built in, but I keep on hearing a lot of saying that don't like it.
Anyone think it's a good thing or a pain? As I have no ideas if it's good or bad.

Our van has it and I have felt it activate a couple of times, when I've taken a corners a little too fast. I like adopt any technology which could assist in an emergency. I would not buy a car without abs and esp now and I see caravans are no different. I am disappointed to see Bailey have removed atc from their 2016 Pegasus.

I seem to think it can only be a good thing, but the person that fitted my movers was saying he's removing it on a lot of caravans due to people not liking it. Seems odd to me.

I suppose one might question the value of ATC same as one might question the value of a stabiliser. Neither of them are intended to make an unstable outfit stable despite some caravanners believing otherwise & it also could be regarded as just something else to go wrong.
It depends how one sees it. From a 44tonne truck driver's pov such devices do seem unnecessary as one is used to driving inherently unstable vehicles within their defined limits, but a car driver may feel 'safer' if outfit has all known safety devices fitted although it could be argued this might give a false sense of security.
I suppose a lot of people don't realise when it is actually working and doing its job. I only realised it when I went over a mini roundabout and it kicked in.

Are we being told HGVs don't have dynamic stability systems these days? I must say that surprises me.
Cars of course do to address solo car instability, though some even have systems to address towing instability. ATC addresses the instability of caravans. A towed unit like a car with a caravan is close to instability, if any disturbance is encountered that can quickly go unstable. With ATC there is a powerful tool to actively correct instability; I have a great deal of confidence in them.
About 40yrs ago anti jack knife devices which gripped trailer pin in the 5th wheel jaws were tried but did more harm than good. Electronic retarders as used on coaches are no good for trucks due to weight penalty which leaves just abs brakes, engine braking & the driver's ability not to turn the truck over on roundabouts etc. An HGV driver will be well aware of how handling characteristics of truck changes with the weight & nature of load. Many drivers do not even like the automatic gearboxes in most 44tonners these days as 16speed manual box gives a better 'feel' on the road.
Accidents do happen of course & no amount of active safety devices will overcome the inertia of 44tonnes enough to affect the outcome.
Anybody who drives only a car may find the technique of continuous forward planning required while driving a heavy truck difficult to understand, the truck driver needs to observe events as far up the road as possible in order to anticipate the outcome of those events as far as possible & drive accordingly at all times. Thats how one needs to drive when towing caravan on the open road.
Its a given that a car/caravan should be loaded & trimmed correctly, just like a loaded truck but many caravanners still believe all an unstable outfit requires is a stabiliser.
Any caravan stability device will correct swaying that occurs in normal driving which drivers may find unsettling but really is harmless, any truck driver knows the difference between normal swaying of the truck caused by road conditions & a potential accident situation.
While a car/caravan has less inertia than a heavy truck it can still weigh several tonnes & logic will tell one that in an ongoing accident situation that anything that grips towball or applies caravan brakes unevenly will not overcome the inertia of over 3 tonnes & may even cause more harm than good.
If a van is loaded correctly and driven responsibly you should not feel it operating. Having caravanned for 41 years without it on 10 previous vans i did not feel the need.But as it was factory fitted when i bought my present van new i have it.The only difference is that now if such a situation arose, it should do its job intended for.
JTQU hgv trailers do have a system thats similair to the atc stystem, It's called EBS gen 2, it works in conjunction with a load sensor and is designed to brake 1 side of the trailer if cornering to fast, i dont know a lot about it as it's quite new and expensive, it also not on any of the trailers i sell.

just like ABS on a car then ...
honestly, nobody drives perfectly and often these devices come into their own when the driver makes an error or we are reacting to the movement of another vehicle. To say you should never feel it working is you drive responsibly is incredibly naive.
I just don't understand the fact that people are having them removed just seems stupid to me. Yes it does come on when you go over a bump ids it or a pain but rather know that it works than jack knifing on a motorway, which I'm sure is scary to say the least.

Did you not read my long post T? People are having them removed because it is a pain when it operates when going over a bump & they know that in case of a jack knife at motorway speeds it would cause more problems than it would solve due to the loss of control caused by the uneven application of caravan brakes. This is why anti jack knife devices on trucks were a failure.

As I said in a previous post I have had it on four vans now .... never had it go off going over a bump and towed many thousands of miles with it.
I have not heard of anyone having it removed to be honest and my dealer hasn't mentioned it and we have had many ATC related chats.
Unless I am being dim it would surely go to stop a jack knife situation happening in the first place.
Anyway I am keeping the faith so to speak. I wouldn't be without it. The fact that insurance companies offer discounts for having it in place shows they have faith too.
