The enclosed trailer GVW is 9,999 so as long as we scale at that or less we are legal. With three mowers on board we are just barely legal. So we don't add much else. The axles are set for that GVW, but not sure which they are. I think they are 5,000 pound axles.
We are saving more than .20 per gallon on off road diesel. All I know is the difference we pay at the pumps. Last week it was $1.56 for on road and .98 for off road.
