When I have used TNT for 5 years, always a semi full of other stuff and they are making a mint.
Same with Wally, who Rob from BikeCity uses all the time, he has always had a full run with both truck n massive truck size trailer chok o blok full so they are making reasonable coin, certainly enough to make it worth their while.

Its not worth anyone doing a long distance run with only a machine so to speak, hence the trucks always being semi trailer or close sizes etc.

I have delivered pins all over the Gold Coast and into Brisbane, Sunshine Coast, Toowoomba, Northern NSW etc, all within a 200 klm distance, and I have charged anything from $80 to $150, $200 max to cover myself n fuel and a helper who gets some fun and $50 in his pocket for a pinball adventure, but its always been for those who want a door to door pin delivery in a specialised trailer.
But when it comes to distances further, TNT or E-Go or Wally is the go !
