Yes, they have to take gradeability into account as well as level road performance.
You will also note that aircon makes a difference because it takes so much power to run, and the weight of the compressor etc is significant.

Oh I agree that they SAY it Martin, but how is it that different engined cars in the same range have the same towing capacity when traction is not an issue? If my Sierra is limited to hill starting a certain weight on a 12% slope, there is no way that a 2 litre car could do the same. I believe that the same applies to the jaguar X Type range. The towing limit is the same regardless of the engine option.

That may well be a calculation made by the manufacturer.
If my memory is at all correct the only legal requirement is that there should be 6bhp available for each tonne of gross train/combination weight.
This may only apply to commercial use, private use seems to enjoy many exemptions.

There was an 8bhp/ton rule introduced in the 1970's, which stretched a few truck makers at the time, especially Scania who had the DS8 engine with 192bhp and Volvo with their F86 engine version. Both uprated fairly quickly to meet the laws, and the larger Scania DS11 engine and Volvo F88 truck had no problem.
I think Gardners only had the 8LXB to offer, while R-R and Cummins were OK.

That was the nail in Gardner's coffin, They tried to uprate the 6 cylinder engine with turbo and a threp'ny bit behind the cold start but reliability suffered. Problem was it was an old design hardly altered over the years and whilst power and revs were at the old standards it was fine but a small increase was enough to find the weak points. Materials helped but physical restraints were still the stumbling block.
All though it's life the engines never moved off a 3/8" diameter valve stem with threaded end. Not a lot of material on this stem for the head size and a nice stress point at the end of the thread.
Interesting to note that the LXB valves changed onto nimonic materials and cut down in length and recut with collet grooves they would fit directly into a Manx Norton and be perfectly reliable at around 7,000 rpm.
They probably don't know it but many 'Gardner's' have lapped the Isle of Man at over the ton <g>

Seema a very peculiar system, how the heck does it apply to truck & trailer combinations? Downunder we have GVW and GCW (Gross Combination Weight) The GCW can be up to 2-1/2 times the GVW depending on the vehicle's tare weight.

Please lets not ask for more interference in our lives. Perhaps you have inadvertently hit on the reason for the proposed regulations in the earlier thread: by effectively killing off rallies they will greatly reduce trailer traffic ! Governments in general and this one in particular seem to suffer the delusion that laws change behaviour. They never have and never will. Exit rant-mode....... Roland

I'll second that. While the current government, though nominally socialist, are more like "wet" Conservatives in many areas of policy, there is an element of Soviet style regulation building up, which I could do without.
There is plenty of poorly thought out, and not particularly beneficial, new regulation on business and on the private individual. On the face of it, much of it appears to be drawn up by the unknowing, with little idea of the practical implications to those who are being regulated. IMHO much of it is political window dressing to draw the public's attention away from important issues and each new regulation just adds a little more grind to life.
In general, if there is an expectation that people will behave well, they usually do. Ebay is a case in point, where the majority conduct themselves decently. It should not be the case that a small amount of shoplifting means we all get searched going in and out of each shop.

Well many MPs, too many IMO, are lawyers so what do you expect.
Moral: consider your candidates' professions before voting.

It's a nice idea Martin but of little use. The thieves have already demonstrated there contempt for the law by nicking your caravan. Do you really think the lack of brake/side lights & indicators would worry them. I agree that the combination becomes a little more obvious to a passing patrol car (only at night) but since the police now rely on cameras the chance of a stop is very low. The other point is what should they do when their lights go out? Stop and try to repair it (if they know how) or carry on and hope? The latter would almost certainly prevail. The best anti theft is a wheel clamp. There are cases on caravan NG where vans with hitch locks have been taken by simply chaining the van to a tow bar. The van is unstable but so what. Since the tow vehicle is generally a heavy van or even lorry, it won't bother it and if the van is damaged, they don't care. After all, it cost them nowt. Let's all try to keep our trailers/caravans.
