Hi Darrin I've been thinking the same lately click below Euan looks like he has it correct . When my tilt- tray moved my carrier home , the truck driver just chained to the two front tow eyes and chained to the rear tow hitch . When I followed behind in my car I could see the carrier hull moving up and down and the chains snapping under tension . On one of my wheels you can see where a tight chain has worn into the cast rim where 60 or 70 years ago it was chained down maybe on a railway car , just like the chain is on Euan front wheel in the photo below .
