Lets have some tales from you old drivers and what you carried in your cabs to keep going in the bad winters of yesteryear besides the number 4 shovel for snow .
I always had a potato to defrost the screen ,yesterdays paper and matches for the intake ,bottle of petrol mix for the ki-gas manifold hand pump besides a cab full of ropes, chains etc ,and always tried to park facing down hill, how about you - we used to see drivers with a bucket of diesel under the sump but i never got as far as that -all good fun at 5 am in the morning .
My old Dad and his mate told me they would stop at a roadworks and nick a lantern to place between their feet to try and gain some warmth during winter tramping, an old army greatcoat was also worn. I know from when I was a lad the Gardner engined Seddon he drove had very little in the way of heat so sacking or similar would be placed over the rad grille, no wonder cafes were welcome places in those days. Franky.
Plenty of beer money and a nice hot drivers mate, [female]

Not so much from the driving trucks world but from a farming front me old man used to tie a “West of England” sack round his waist as no heated cabs on tractors back then either, it was a warm addition in harsh cold weather, cut open they made a good make shift horse rug as well, Buzzer.
