Weighing your rv

I hear it said a lot that when you weigh your unit you should weigh each wheel vs just the axles and that makes perfect sense. With that being said how do you do that? Is this possible at the cat scales? Those of you that did it how do you do it?

    The Escapees club has a couple of 4-wheel weigh stations at some of their parks, and has a traveling unit that goes to many of their rallies. What we've done is find a scale that's not too busy and flat to the ground. First drive thru and get a total rig weight and individual axle weights, then drive thru again, offset enough that only the wheels on one side get weighed. A little math will then give you the individual wheel weights.

    Sounds like a great idea, except it is extremely hard to get repeatable numbers. Each time you side step the scale to reweigh if you move the rig a few inches from where you weighed the last time the numbers will change. Those platform scales are not designed to be side stepped that way. Much better to find a guy with the individule scales and weigh correctly at each tire location, 4 corner weigh.
  • I've only noticed a few CAT scales, but the ones I've seen wouldn't have room to only weigh one side. The ones I've seen have a framework that goes from one side to the other that has the microphone/speaker mounted on it. I suppose you could back in but that looks like it would get really complicated.

    I bought a Shurline scale to do mine. Works a treat.
  • Another place to consider is a landscaping supply company, one of those places that sells rock/soil/mulch/etc in bulk weight. Their scales are usually very open so you could accomplish that offset thing you want to do. I did this locally (not the offset) in multiple passes/weights on a day when they were not busy. They didn't charge me anything at all, but you can bet that I will be using them always for my landscaping projects business.
  • Most CAT scales have enough room on the side for you to take a second pass with just one side on the scale. The console is even set up for this, asking if the weighing is the initial weight or a re-weigh. I think the re-weigh option is for truckers that reposition the trailer axles and try again, but it will work for a second pass of a motor home as well.
  • Some, and probably all, moving companies have scales. Some where you can get several weighs by moving around with portions off the scales. My first coach was weighed that way. Think the guy charged me $8.

    That's a great idea driving offset like that. Never gave that a thought.

    Thanks
