In the last issue of the magazine, there was a picture of a nose wieght gauge attached to the jockey wheel, small round always mounted, can someone pleases tell me where, to find such an item, need presents for christmas.
Jockey wheel nose weight gauge

L...I think the one you have seen is part of a new type of jockey wheel that has the nose weight attached.
If you want you can buy a standard nose weight gauge from any caravan dealer or from the online shops. From memory mine cost about

is this it 1221695 - Premium Jockey Wheel with Integrated Nose Load Gauge http://217.199.167.226/shop/acatalog/Jockey_Wheels_Accs.html
Just a word of warning, i saw these advertised somwhere and thought thats a good idea, untill i found out how much they would add onto my noseweight,

Hello L,
I am not familiar with the unit you are asking about, but it must be realised that the load measured at the jockey wheel will be different to the load measured at the tow ball.
This is because the distance between the road contact of the main wheels and the stem of the jockey wheel is less than the distance between the road wheels and the ball hitch. The greater the distance the less the imposed load. (GCSE levers and forces)
Fortunately, because there is a fixed relationship between the distances, it is possible to calculate the true hitch load by multiplying the measured figure by a correction factor.
It is also very important to adjust the height of the jockey wheel so the height of the caravan nose is the same as when it is attached to the car, and the cars springs have settled before taking a reading.

Although John is right in saying that load measured at the jockey wheel is not the same as the noseweight, the reading that you get will always be higher than the actual figure, so there is less likelihood of exceeding the limit set by the manufacturer if you do not correct the value, as John suggests. So, one can consider the jockey wheel gauge to have an in-built safety margin.
As with any measuring device for nose weight weighing, it is only there to give you a guide so that you are not massively outside the parameters.
The difference between measuring under the hitch or under the jockey wheel is minimal. I checked my van using both methods and got no more than 2Kgs difference.
As with any weighing device, unless it is regularly calibrated by the manufacturer or a guage calibration company, you can throw out all the technical bumf. As without an uptodate calibration certificate it is only a comparitor and not a guage.
On a SAFETY NOTE please don't go trying your "pogo stick" weight guages anywhere else other than driectly in the ball hitch cup of your van. I had a serious accident 2 years ago while using one of these deadly weapons.
Because I'd forgotten my piece of rag to keep the end of the guage grease free, I elected to place the guage under the hitch on what I thought was a flat surface. On winding the jockey wheel up I bent over the guage to take the reading and POW!!!
It took off with 95Kgs force (that's what I recall the weight being) and smacked me in the face just below my lower teeth.
I ended up with two chipped teeh, a split lip requiring 5 stitches (done without anesthetic) and a lower lip that has no sensation for an inch across the front center.
Luckily for me, we were caravanning with family friends and I had a retired ambulanceman and a qualified nurse plus two first aiders on hand, together with a very well stocked first aid kit.
Needless to a trip to A&E was also needed.
Having bin'd the pogo stick I now have a very neat compact hitch weigher that fits onto the car tow ball and also fits into the caravan tow hitch cup. While this put's the hitch height about 100mm above normal travelling height it does give a much safer weight guide.
While it's a macho thing to of found out that I can survive a near 100Kg upper cut, the pain I endured after is not easily forgotten and I certainly would not like anyone to have to go through that.

I read the write up on these jockey wheel gauges and got the impression that the magazine was not overly impressed as you had to use a formula to calculate the actual figure,too much trouble me thinks.
Thank you all for the information, we are looking as one person said to be within the ball park and not over while towing, we even know that when the nose weight is done you are not moving, and the weather is dry, the wind isn't blowing, and the sand hasn't shifted, but we are looking for a quick and easy way to tell that we are somewhere under the weight, after figuring the varitables, and that if necessary before moving off that we can move all the soveniers and are very close to being balanced correctly, for us this seems like the ideal solution, and we will take into consideration everything, everyone has said. So again thank you.
