Default 1800 SR3 trailer issue

I have a 2007 SR3 which came as standard with the purpose built Karavan single axle trailer. (Maxum specific variant)

US-2800-SB-74-ST-GL

I was looking up the Tyre pressures.
The tires are Radials 205/75 D14 F 78-14ST 6ply

In the karavan manual the table gives the rating for maximum load as 1760 lbs (@ 50 psi) - 3520Lbs per pair


Which started me thinking about he weight of the rig:
Boat + 4.3 engine + full tank fuel 2885 lbs

I then looked up the VIN label on the trailer ... it advises that the maximum load carry capacity is 2859 lbs ???

That means with no equipment, a boat with nothing more than engine it was upplied with and a tank of fuel exceeds the carry capacity of this trailer ?

Are Maxum deliberatley using wrong size of trailer ?

Is there a Maxum tech help line I can email on this ?

Funny that you're worried about your trailer; what's the unbraked towing capacity of your vehicle?

Chances are the wholes rigs illegal...

Actually, no its 750kg. and its 750kg's for a reason.

You can tow 2.7 tonnes on UK roads with functional brakes... but you don't have any, therefore a small overshoot on trailer capacity if the very least of your worries.

I thought the American trailers had hydraulic brakes? still illegal in the UK but still braked or have these been removed?

If installed: They're illegal

The American braking systems are totally different to the UK ones, in that they are often controlled electronically - from the car. The UK cars don't have this controller therefore, the brakes might be there... but they aren't doing anything.

If it had surge brakes yes - but even then, those brakes aren't technically legla and require servicing - which no one ever does, especially 2nd hand owners and beyond.

The other thing is that it DEFINITELY won't have a hand brake, so should you encounter trouble, or be the spotter on a slipway... you could find serious issues. The trailer should be able to stop independently of the vehicle.

Generally, freebie trailers with boats under 20ft though will just be 'launch trailers' and merely a basic set of hubs bolted to an axle.

This is the whole problem with bringing a none UK trailer in to the UK... leaves so many questions unanswered and the public at large aren't informed as to what their boat is sitting on. Which, if not UK supplied, in almost every single case is illegal - may as well have not bothered insuring your self should you have an accident....

Sorry to rant, really don't want to cause any offence... its just I see these trailers at work so much and it really angers me - they are an accident waiting to happen and an absolute nightmare as there's so many about now.

I don't understand what you mean here ? .....
The figures I quoted are correct for trailer and for car ... and it is a braked trailer.

The point is the maximum carry capacity of the trailer is exceeded smply by having a full tank of fuel ..... I have contacted Karavan Trailers and they conform that this is being exceeded.
