Caravan Motor Mover Bolt Field Report
Our Motor Mover Gave Up Halfway Onto the Pitch in Front of the Whole Site. The Fix Was One Bolt I Could See and Could Not Turn.
July 2026 · 8 min read
Thirty-one years at the works for this. Then one bolt nearly ended our season in front of a full site.
If you tow a caravan, or you run a motorhome or a campervan, there is a bolt underneath it right now that you can see but cannot turn. You do not know about it yet.
But the first time your motor mover starts slipping halfway onto a sloped pitch, or a corner steady seizes solid and will not wind up, or the spare wheel carrier will not drop in a lay-by two hundred miles from home, you will find it. And you will find out that no ratchet, no flex-head, and no wobble socket in your boot can reach it.
I know, because I spent the better part of a day under our van on wet grass proving it.
When something lets go on a van, it is not a hobby. It is your home.
My name is Colin. I am sixty-six, my wife Jean is sixty-four, and I spent thirty-one years as a maintenance fitter at the steelworks in Rotherham. The month after I finished, we bought a 2019 Bailey Unicorn with a motor mover and started doing what we always said we would. The Dales in spring, Cornwall in June, Scotland in September. It is the life the brochures sell. Most days it earns the brochure.
We were at a full club site in Wensleydale on the May bank holiday. Every pitch taken. Ours sloped down towards the hedge, so I unhitched on the roadway and set the mover to walk the van on, the way I have done a hundred times. It got halfway. Then one roller started slipping, the van slewed crooked across the pitch, and it stopped. Dead. Half on, half off, sat at an angle you could not hitch a car to. And everybody coming back from the shower block could see us stood there looking at it.
I have worked on machines my whole life, so I knew it before I got the torch out. One of the clamp bolts holding the mover to the chassis had backed off, a few thousand miles of motorways and potholed lanes will do that, and the roller had eased away from the tyre. I could see the bolt. I could get two fingers on it. But lying on my back on the grass between the chassis rail and the floor, there was not enough room to get a ratchet on it and swing it.
Every tool in the boot. Here is what each one did.
- Half-inch ratchet. The handle hit the chassis rail before the socket would seat.
- Stubby ratchet. Maybe a few degrees of swing on a bolt that needed a proper pull.
- Flex-head ratchet. Bent in, seated, then folded the second I loaded it. I skinned my knuckles on the rail.
- Universal joint on an extension. Deflected sideways and twisted off the bolt head every time.
- Wobble socket. All angle and no torque, which is exactly backward from what that bolt needed.
The mobile engineer: three days out, a call-out fee, and the dealer wanted £249
I rang the mobile caravan engineer the site warden recommended. Three days out, minimum, it being a bank holiday. Fifty-five pounds just to come out before he turns a spanner, with labour on top. The dealer that fitted the mover was worse. Two hundred and forty-nine pounds to strip and refit it, first slot in three weeks, and the van has to come to them. Which is a neat trick, because the van was sat crooked on a pitch it could not leave.
I crawled out and sat on the step. It was starting to drizzle. Jean brought me a sandwich and a cup of tea and did not ask how it was going, because she could see it. She sat down next to me and said, we will sort it. She has said that every time this life has thrown something at us, and every time she has meant it.
On my back on the wet grass between the chassis rail and the floor, looking at a bolt I could touch and could not turn.
Then a retired caravan engineer walked over from a few pitches down
The next morning a bloke called Ted came over from a Swift motorhome a few pitches down. Seventy-two. Thirty years on the line at the Swift works up in Cottingham, where half the vans in this country get built, before he retired and took to touring himself. He looked at the mover, looked at the bolt up in that gap, and nodded the way an old hand nods at a story he has heard two hundred times.
He came back with a solid steel bar about fourteen inches long, square drives on both ends, a fixed bend in the middle. He had me press my thumb inside the drive end. Something moved. A roller chain, running the length of a sealed steel housing.
"The chain takes the bend for you."
The body holds the shape and the chain carries the torque dead square to the socket, no matter what you put on the handle. Ted told me he has set more mover clamps, corner steadies and suspension bolts with a bar like this than he can count. Not one rounded. Not one van sent back to the dealer.
The sealed chain is the trick
A roller chain inside the steel body carries torque around the bend, so it never folds like a flex-head or walks like a u-joint.
Fits the under-an-inch gap
A slim flat bar slides into the gap between the floor and the chassis where no ratchet can swing.
Your own sockets
Square drive on both ends takes the sockets and ratchet already in your boot. No proprietary anything.
It reaches. It is honest.
This solves access to a bolt you cannot get a tool on. It is the right geometry for the gap, not a miracle for a bolt rusted to nothing.
It only comes from one place
You will not find it at Halfords or Towsure, or on the parts counter at any caravan dealer. The maker sells direct from their own site only. Sixty-nine pounds, shipped tracked to your door anywhere in the UK. That is less than the call-out fee plus the first half hour of labour, and a rounding error next to the dealer's two hundred and forty-nine, a recovery truck, or the weeks of the season we would have lost.
What happened next
Other caravanners who stopped paying for access
"Mover started slipping on the drive at home and the clamp bolt sat in a gap I could not get a ratchet into. This bar set it in two pulls. Cheapest fix in forty years of towing."
"Corner steady would not wind up and the bolt sat behind the cross member. Mobile engineer was booked three weeks out. Did it myself in twenty minutes."
"Bought the cheap one off eBay first. Folded on the mover clamp bolt. Bought the real one with the chain. Chalk and cheese. The chain is the whole point."
Ted learned it from a bloke at a rally. Now he keeps a count, and he is passing it on.
Get yours before your next pitch
If you tour half the year, or the van sits on the drive waiting for the season, and you have ever laid on your back under it looking up at a bolt you could see but could not turn, now you know there is something that reaches it.
