leg oot the bed · Dec 27, 2020

Evening folks, I have the chance of getting my greasy mitts on a brockhouse 1 ton, I've not had a chance of viewing it yet but it appears in generally decent nick, done a few hours raking the internet, I found they are 750mm to the tow ring and if I were to fit a nato hitch it would be 650mm to my hitch, I have a td5 110dc, I was wondering if anyone had used one of these trailers on a 110 or similar, or anyone had changed the axle to drop the height or if it would be sacrilege to interfere with a bit of old mod history, did also consider fitting a modern set of tyres like a 235/65/20 to drop the hitch height as original tyres are 9.00xr20 at 37" but I assume the original rims are tubed, any info would be appreciated

Its my understanding that trailers should be slightly 'nose down' so 100mm might be ok. I'd get the trailer then work out the technicalities later!

The angle of the trailer doesn't matter all that much, so long as the back of it isn't dragging on the ground.
What is important is that there is a positive noseweight on the towball.
If the trailer is lifting the vehicle, it can be pretty much undriveable.

A clear explanation thank you.

Never used to bother me too much. Obviously, you don't want too much weight on the back of the vehicle, especially on long journeys, because the tyres will heat up, even when pumped up to 40 psi.

But when I used to tow loose cattle, which can walk around in the trailer, even with a partition in to keep them forward, I would aim for a noseweight of about 100kg. The method I used was to load the trailer, and if I could lift the towhitch on the trailer at all by hand, I would be worried.

On the other hand, even a negative noseweight of 10kg would be a serious concern.

yea rit’s a good measure of nose weight, or on a single axle trailer if the draw bar tries to chin you then it’s loaded wrong

I once picked up some galvanised roofing sheets with my Ninety and a single axle trailer, the body of the trailer was 5 feet long, and I loaded the 8ft sheets hanging over the rear. The lift on the towball probably was no more than 15 or 20 kg.

I thought it would be fine, because I was only going a few miles on local roads, and one junction on the by-pass, and I wasn't intending to go more than 40 mph.

But when I got down the road, and went round a bend, only doing about 30 mph, the back axle of the tow vehicle stepped out, and the trailer skidded as well.

Luckily, the road was empty of other users, but it certainly taught me never to tail load a trailer, so now, I don't!
