Who weighs?

I weighed rigs for 8 years while traveling full time as a side line job. People who had tire issues searched me out to see why the tires were failing. Many rigs are not anywhere near evenly balanced side to side. It was not unusual to find 800lbs to 2300lbs difference side to side or one one wheel location. Having a rig roll over a CAT scale would never show these side to side imbalances. If for nothing else the owner knew how his coach/trailer was carrying the weights. Did weights change, sure but every single thing inside that rig has a weight attached to it, and where it sits or is mounted makes the carrying capacity different. Some coaches right out of the factory were heavy on one wheel position before anyone even added their personal items. You don't want to know how your rig is carrying weight, your choice, then don't get weighed, but getting a weigh by wheel position will at least let you know what it is you have. I no longer own the weighing business but see the need for this service. It is very difficult to get it done other than at an RV rally where a person has invested the 7 to 10,000 dollars in accurate scales designed to weigh each wheel position. Folks that do this type of weighing have taken the time to understand the ins and outs of weighing to give repeatable numbers. Driving off center on a CAT drive on scale is not the way that scale was designed to weigh, it is a drive on, meaning all wheels not just one or two. Just my 2 cents.
