Took the caravan out for its maiden voyage over the weekend. Just over an hour from home, lovely site just the other side of Builth Wells. Towed fine but noticing a little pitching on the caravan on the well surfaced country roads :-) .Towing with a Boxer van, so all the kit and awnings etc. in the van. Should I be checking the nose weight very closely to improve the stability on the road. As I say not too much additional weight in the caravan. Caravan is just under a 1000kg unladen. Sat quite level on the road when hitched up. Can I assume a little more weight on the nose would counter the pitching. Any advise much appreciated.

Ideally you need to know what the towball weight limit is for the Boxer van then with a noseweight gauge aim for that figure. However, you don't say if you had a stabiliser fitted or not because if you do then the maximum weight limit is 100 kgs. anyway. If the noseweight is too light then you will definitely encounter some instabilty problems because the damper directly behind the hitch operates the caravan brakes so if the noseweight is too light the hitch doesn't compress the damper efficiently and tries to ride up over the towball in effect. This obviously can lead to snaking because the damper doesn't compress the caravan brakes which then fail to hold the caravan back. The correct noseweight will also eliminate the pitching as well.
Most caravans tend to sit slightly nose down when hitched up. I wonder if your towball on the Boxer is a little high.
The wind pushing on the front of the caravan tends to lift the front slightly decreasing nose weight while driving. In your case this might make it a bit nose up and this can affect stability.
Could be. It can certainly be adjusted down by 60mm or so on the mounting. Have to try increasing the nose weight, take it for a runaround on the weekend and then drop the towball to see what works best.
On another subject, found out why it is giving the familiar clunk on the hitch when braking in to roundabouts/junctions etc. The damper wasn't operating the brakes until fully compressed. Adjusted it up on the centre bar so will test that over the weekend too.
Checked the nose weight today. Spare wheel and full 4.5kg of gas in the front stowage and not a lot else gives 85kg on the hitch. Caravan already a bit nose down so won't drop the towbar yet. Popped another 15kg in the front stowage by adding a trolley jack and a water container half filled. Going to take it for a spin tomorrow now the weather has calmed down and see if it tows well. Off to the BSB at Oulton Park next weekend so be nice to get it towing well before the trip up the A49. Any tips on where to get a good breakfast between Hereford and Oulton much appreciated.
Sounds like you are starting to put to much weight on the front now. Do you keep stuff in the caravan over the axle, it does not take much to make a caravan pitch if there something stored at back of caravan. I find I get a little bit of pitching when first hooked up but settles down after a couple of miles.

You are right what you say but I thought this was whole the idea of checking the noseweight. Once the downward towball weight limit of the vehicle has been found out then they OP needs to aim for that target then pitching or instability won't become an issue. That applies to anyone who is towing a caravan.
Took the caravan out for a run today and definitely better with about 100kg of nose weight. Towing at 50 on a well surfaced road is fine, just a bit of pitching at slower speeds on average roads. Can't find a definitive recommended noseweight for the Boxer van and the towbar SN is marked na which is a bit annoying. I suppose it isnt an OEM towbar so the noseweight isn't definitive for it. A search around the internet and various forums indicates 100kg as around the weight to aim for but it always depends on how the caravan is set up I suppose. No additional weight over the axle or in the back, just weight on the nose to get that right first. Bearing that in mind perhaps it needs weight over the axle to bear down on the suspension a little especially with tyres at 52psi which is the recommended pressure. Lynn's Raven Cafe, Junction, A41/A49, Prees Heath, Whitchurch SY13 2AF Will definitely give that a try, should be ready for a bit of breakfast by then :-)
The downward towball weight of the Peugeot Boxer van has two limits apparently. If it's the step in bumper version then the towball weight limit is 80 kgs. and all other versions are 150 kgs. but if you have a stabiliser fitted then the maximum weight allowance on that is 100 kgs. anyway.

Its the 150kg version then. I have a stabiliser ready to fit but will probably leave it till after the weekend and see how it behaves first. Thanks for the info.
