After much searching I finally found an MS3 truck which just required a couple of tyres fitting in order to use.
Unfortunately the moment I placed a wheel on it, the truck started to bounce around uncontrollably.
I managed to remove the wheel again hoping this might stop it and I even exited and tried restarting the server.
Sadly this didn’t fix the issue and after a few minutes the truck eventually flew into the air and is now hovering in the sky.
I’ve also had the issue whereby (after I found another truck) I was unable to load anything into it.
