Your range rover sport is an extremely heavy car, tipping the scales at around 2.5 tons, so I don't for a minute think the nose weight of 150kg would have any effect at all. 2 ponies, depending on size could be 750kg+, plus whatever the trailer itself weighs (300kg?), so 150kg on the nose surely is fine.

Regarding centre of gravity and weight distribution, with 2 ponies in the back, I'd expect you to be driving like you'd a 4 tier wedding cake in the back, i.e, very very careful and gentle acceleration, braking and cornering!

I had a Dutch built twin axle double horse box, which i towed behind my old Landcruiser many moons ago, probably a similar size and weight to the Ifor but it had indy suspension.

Anyway, the thing is with twin axled trailers is that they have a natural hitch height, unlike a single axle, so ideally your towball height wants to be right for the trailer as it sits naturally, you can buy adjustable drop plates but they may not be suitable for detachable towbars, hopefully yours will be right straight off.

Other than that horse boxes are very stable for towing, i could travel at quite unmentionable speeds, without horses on board obviously, and the combo never twitched loaded or not.
