Hi guys once again I’m asking for your opinion here.  I’m in the process of buying my first caravan and I noticed most of them have axle right at the center of the caravan, like the Penta and Sprite range. When I looked at the Gypsey Regal, I noticed the axle is positioned more towards the back.

Does this position changes the stability when towing? My gut feeling tells me that the Axle more towards the back gives more stability.

your thoughts?

Hello Rodrigo, 

The positioning of the axle on a caravan is a relatively complex matter, which affects several factors on the caravan including, Stability  and  ball weight, both of which are also affected by the way  you pack your van, ( weight distribution ) as well as tyre pressure of both the van and the towing vehicle,   also having an effect is the speed at which you travel.

If you Google Positioning the axel on a trailer there  are some interesting articles  and videos on this subject.

Good luck and "Stay Safe."

Rodrigo, I tend to agree with you and with Brian.  But the fact is you haven't got a choice on where the axle is located- as Trump says, it is were (what) it is.  The most stable would undoubtably we with the axle far back, like in a boat trailer where the most load is at the back of the boat anyway making it possible to have the axle far back, but with a caravan you would then have a massive load on your tow bar.  So manufacturers have to compromise to reach a managable solution.

The basic's was mentioned already.  As in life there is a trade off for everything.  We must just remember that the pack and load of the caravan/ Trailer is solely the responsibility of the owner.  Jurgens really did not leave much margin for error to the owner though.

With regards to stability of a trailer of which the axle is more to the rear I will also go with what has been said. But the trade off is nose weight.

Just a point of interest, the further the axle is to the rear of the caravan/trailer the easier it is to reverse with that caravan/trailer.  As the tendency of the caravan/trailer to jackknife is reduced the more the axle is positioned to the rear.

It is all about load distribution. The caravan design will dictate the best position on the set van.

Then it also depend on how you load your own content and placement thereof in the caravan

Also note that most Caravans load is 200 kg or less

If alteration was made to the inside of the van it will behave different to the OEM model

Then Nose weight is also of interest   the recommended weight is 100 Kg, but most tow bars allow only 75 kg

As does the RTA (Road Transportation Act) got restriction and said weight

Ek het geen probleem met die posisie van die Fleetline se as-plasing nie, maar ek moet noem dat my Metalian 4x4 wa se as verder terug sit as die algemene 4x4 waens. En ek het net plesier met die sleep van die 4x4 wa. Ons was al in die ergste omstandighede met die wa. Ek het per geleentheid n Echo-treiler einaar gehelp met die haak van sy wa. Die Echo se as is in die middel van die wa. En toe ons die wa nadertrek toe tip die wa agter-oor, iets wat nie met my wa kan gebeur nie.

Ek onthou in die ou dae toe ons n Jurgens Champion B gehad het was ek letterlik geforseer om n Trapezium te hê. Maar met die Fleetline sleep ons nou al heel lank sonder dat daar enige swaai-probleem is.

Ek dink tog my Fleetline gaan baie swaar wees indien die wiele meer terug was.

En nog iets, waar presies  is die "middel" van die karavaan? Lê dit tussen die haak en die agterkant van die karavaan of lê dit in die middel van die woon-deel?

Hi Rodrigo,

I have a 2014 Gypsey Regal and I tow with a 2011 VW Jetta 5, so the Jetta is already a low car and if the weight is to much on the ball I will hit the bumps in the road, so all that I do is I start packing above the axle and then move away from that point to the back and front of the caravan, i have then found that the nose isn't so heavy, so it's all about weight distribution.

Hi Rodrigo,

I do use the yellow blade stabilizer, as the first time I went camping with the van it did sway a little as the trucks and busses past me or I past them, it would sometimes pull or push at the van, but might of also been the way that I packed it at first, after that trip I used the yellow blade and pack on the axel first and then moved to the back and to the front, otherwise it's a really nice van to tow, my last tow was all the way up to KNP phalaborwa gate as I was camping at Letaba and all the way back to Benoni, was a good trip.

Weight distribution

Interesting to see so many comments in this tread. I found an interesting article (see link below) clarifying some questions, but yes it is a complex matter. I created this topic simply because I'm deciding on the Penta and Regal and I noticed the difference on the axle position. It is all about Newton's law and the pendular movement. As per the image, the bigger L6, more stable it is. The smaller L4, more stable it is. We can't change the L6 but we can pack the caravan more efficiently. Also, the heavier the towing vehicle (compared to the trailer), more stable it is.

Thank you for all your comments, it is being really great to learn from you all.
