What was the name of the film with Sly playing an USA trucker,he had a gym in the back of the tractor unit,with bar bells and a rope and pulley weight system,to use when he was driving along.Could catch on in the UK.Do some reps when sat on the VOSA weighbridge.Or at a RDC for hours. 
o.t.t. i think
I remember it was to do with arm wrestling but not the name of the film
it was Over The Top made in 1987
Just asked my mate Google and he says it was Over The Top (1987)
A quote from the film by Stallones Character Lincoln Hawk
Tell you the truth, the truck is, uh, you know, the most important thing for me. I… I don’t really… it doesn’t matter if I, uh, become the champion or anything. That’s, that’s not the most important… I… I need this truck.
Black Dog with Patrick Swayze was not a bad film,Meatloaf in it too.
Over the top the whole film is on youtube and good quality
