Winseer:
I always leave a gap, but not as much as two inches.
It was a shunter so I wonder if they were using a tug and still had the fifth wheel raised a bit.
Bking:
Tell the shunter to stick it where the sun dont shine
Your trailer is over there mate…
Up to it’s axles in water and dropped as low as a California low ride car on a Saturday night.
Good luck getting it out.
respect your shunter
