Those vans have a very high centre of gravity compared to the more normal 3.5t conversion with a low floor pan. They give a very unstable ride because of it. I wouldn't, personally, want to carry a big horse in one.
To find out the payload, there are lots of places that will weigh it for a small fee. Places that sell aggregates normally charge about a tenner.
Sorry that's not the information you were asking for, but I hope it helps.
Totally agree with ycbm's comment about stability, I knew someone who had one of these and it didn't give a very peasant ride, also the ramp was incredibly steep.
I wouldn't put a horse in one of those for the reason mentioned above, I would find a horsebox where the horse stands below where the wheels sit and not above them, I had an old N reg Renault master 3 5 ton and that took a 16.1 horse in there no problem, some do have lower roofs so I would ask for height measurements just to be sure.
Thank you every one, this is my first horse and so will be my first box, i have been looking at van conversions, but again i dont know which ones will carry a 16.2/3 horse ☹ï¸
I know of someone who has the same/ very similar and was happily travelling a 15.2 & a 14.2 in it. Out of the blue decided to take it to a local weighbridge and discovered it only has a 500kg payload, so not enough enough for her 15.2
She's still travelling the 2 horses in it because the replacement 'doesn't arrive until October and it's only short journeys' but that's another story...
Of course they may not all have a tiny payload but it's something to bear in mind.
Firstly, what does your 16.2/3hh horse weigh? There can be more than 150kg variance between a lightweight TB and a heavy ID. When you know that and then make allowance for the number of passengers, diesel, tack, water and anything else you need to carry you will have an idea of the minimum payload of the vehicle you require. It's best to work that way and DON'T accept what people tell you is the payload....ask for a certificate or when you go to test drive it, take it to a weighbridge.
thankyou, i think he weighs around 600 he is a welsh x hanoverian i know it will only really be me when travelling so i was thinking around a 1-1.2 ton payload? Which i know some vans have but dont know the internal space he will need
