Noseweight advice

As said before MM. I would be happy to tow up to 1350kg mptlm with towball weight of 75kg. but not a 1600+kg van

Are you using as high a pressure as is allowed on the towcar's rear tyres?

I ask because getting particularly the rear of the car as stiff as possible to sideways deflections is a powerful characteristic in towing stability. Inflating the tyres to higher pressures will increase that important stiffness.

Whilst it might not be the issue it is something so easy to try and will help to some extent.

I tow a Coachman VIP, replated to 1700kg, with a Landover Discovery Sport and previous towed a Bailey Unicorn, which was lighter, with the same car. I have found a nose weight of 85-90 kg necessary for stability with both caravans.

I am surprised at the problems you are having. I tow an 1800kg single axle and the towcar's noseweight limit is 80kg, but don't have a stability issue.

But probably that is of a continental design with a long draw bar dimension together with a long "A" frame before the van's bodywork, both stabilising features? 

Thanks for the advice and comments. I have used maximum pressure in the tow car's rear tyres but it looks like the only really safe option is to reconsider my choice of caravan or towcar. I really like the Kodiaq in all other respects so will probably try to trade my Coachman for a lighter van. 

I too have a heavy Coachman, but its fine behind my heavy Coachman. I suspect my nose weight is heavy but have never really checked, with my car its not an issue.

But  your van like mine is a heavier model Coachman, and from 2015 they made lighter vans.  I wish I had waited because I like the brand!

I find it best to put my heavy Coachman behind my heavy tow car  😉

as they say. " sarcasm is the lowest form of wit"

I was pulling Tiger's leg ..... I know he will have taken it as such too
