Bulk grain tipping - tramping

Anybody with any experience of this?
Looking for a career change already, sick of ridiculously stressful 12 hour days in London doing super market work.
The big shops are easy and stress free. But majority of it is tiny stores in central London full of awful driving and people parked in the only area you are allowed to unload for 20 minutes - laughable.

Anyway looking to get away from this and found a company with a vacancy doing bulk grain and you spend 4 nights out a week… what are people’s thoughts on tramping and bulk grain work in general?

Cheers

Double post my bad
