Solasosa,
I live near some Interstates where truck oriented gas stations usually have scales. I have one only 6 miles from my house off I 26 and quite possibly other ones near by. I am a new Hi-Lo owner and plan to have my RV weighed at the nearby scale. Knowing nothing about the procedure or cost, I stopped there the other day and talked to a trucker who showed me the three different scales (you can visually see where each of the three scale platforms begin and end) for measuring the three axles on an 18 wheeler. With my Hi-Lo I think I could place my truck on one scale and the Hi-Lo on another to determine those two weights. I don't think my Nissan truck wheelbase is long enough, and I know the Hi-Lo wheelbase is not long enough to determine each of the 4 axle weights. Others on the forum have already used these truck scales and know a lot more than I do, but I'm saure you could determine the weight of your Hi-Lo trailer using this method. The trucker said that after pulling your rig onto the scales, you push a button and ask someone inside the gas station to print out a weight report for you. He thought the cost was $7.00
I wonder if there is a way to determine tongue weight using those scales?
