If you just wanted to slink along at a slow pace, the one position in 4 low is kinda like a creeper gear on a tractor. You could get out and walk beside it without it shifting into second and making you trot.
Also there may be scales closer than you think. Try your local dump sight, they sometimes charge by the weight dumped. That’s where I had to go to weigh a trailer with out of state plates to get registered.
