Hi All. I recently bought a double-axle caravan for the first time. I have noticed, though, that the weight on the tow-ball (nose weight) is very high, even with an empty caravan. Then I also noticed that the positioning of the 2 axles is not in the centre of the caravan, but rather to the rear. In fact, the front axle is almost perfectly in the centre of the caravan's length. This seems odd to me, as I would have thought the axles would have been in the centre, so that the nose-weight would be minimal, and the caravan would then "balance" itself quite well on it's 2 axles. One can even argue that the rear axle, when on uneven ground, can push even more weight onto the nose! Has anyone else found the same issue, or had any problems with this? Thanks!

This is the engineering designs for two axcel trailers.
Axle Placement for a Tandem Axle Trailer, else you wil have a centerline between the wheels and the will swing around that no matter what you do. You need the Axcel's to drag behind the centerline of the box.

Measure the total length of the box(A) and divide that dimension by 2 to find the centerline of the trailer box. For each foot of total box length(A) move the centerline of the axles(B) toward the back of the trailer 1 inch from the centerline of the trailer box. That axle centerline is where you will attach the middle spring hanger. Be sure to position front and rear spring hangers according to manufacturers specifications. Be sure to pull diagonal measurements from the middle spring hangers to the coupler to be sure that your trailer will track straight. Example: For a 12' trailer box(A), the centerline of the trailer box is 6'(12' / 2 = 6'). Since the trailer box length is 12', the centerline of the axles will be 12" (or 1') towards the rear of the trailer from the centerline of the trailer box(1" per foot on 12' box length). So the centerline of the axles will be 7' from the front edge of the box. For a trailer with excessive tongue weight, you can cheat as much as 10-15% toward the centerline of the trailer box to compensate for the tongue weight. Be careful not to over compensate because without proper tongue weight, your trailer can become a mobile disaster for you and anyone else on the road. This method should only be used if you will be hauling evenly distributed loads.

Also found the noseweight high even with an empty van.
I sort of ignore this fact as there is'nt anything to do about it.
The most of the load is in the back of my JEEP. Tents. Boxes with pegs. etc etc etc.
Just fridge contents and clothing in the van.

Sorry, just forgot to mention. I dont carry the gas bottles with me anymore. Only if we are going away for 2/3 weeks and then also in the JEEP.. so the nose cone is packed with the sparewheel and some other lightweight goodies. Fishing rods etc etc.

Gas is used for pancakes. If there is a power dip.... then its extra motivation for a braai.

I have the same problem. The weight on the nose is more than the legal limit.

Thanks Gus, for your explanation. That makes sense - I didn't even think of that! The question then is: what can be done to reduce the nose weight? Not much, as Oom Jeep says. Packing more weight towards the rear is not a great solution, as the tendency for sway/instability increases. I think I need to ask Jurgens their view on this... I'm very surprised by this situation, as there quite a lot of double-axle caravans around these days, and I'm sure they all have this problem.

As you can see I tow a double axle Sensation Maia and I do not have this heavy nose weight.  To be honest the nose weight of my van can be regulated by how much I pack in the frontend of the caravan. How I came to know this is when I fetched my Maia from Sensation nothing was loaded in the van. I used the mover to bring the caravan out from display area of the factory. It has a rather steep down slope just as the glass doors.

The jockey wheel lifted of the ground as it passed over the doorline and stayed there until I slowly pushed the front axle over the doorline then only did it drop slowly as the van moved forward.

I even found that when reversing the Maia from my drive way the jockey tends to lift a wee bit as the two axles pass through the ditch where the tar and pavement meets. Again with nothing loaded in the front of the van.

Now with the spare wheel and either the Rally or full tent there is enough weight that alows for a stable tow.

So with without anything packed in my van it will run balanced only on the two main axles.

The one item to look at is the maximum weight the vehicle's towbar is designed for.
In my case it is a 120kg restriction on a Pajero.
In the case of my Sensation Vee I had to move all the tent stuff to the Sensation's boot area to get to get to 120kg in front. It is evident from all the letters which were published in the forum, that this is one issue which the manufacturers ignore.
With single axle caravans you can put the stuff behind the axle in the inside of the caravan - bit difficult.
On Youtube there are videos which show the effect of unbalanced caravan loading.

Mine is on 120kg. I pack so that most of the weight is over the axles, the two gas bottles goes in the tow vehicle and only very light stuf under the bed.
