RV FEATURE This portable fridge was accounted for, too. WHAT ABOUT GCM? This is the big one, the figure that arguably most vanners overlook when hitching up and heading off. We know the loaded weight of the van is 2290.14kg. As this figure also includes a 200kg ball weight, we don’t need to count the 200kg again when adding 2290.14kg to the loaded weight of the vehicle. Therefore, the equation is 2290.14kg + 2470kg = 4760.14kg. This is 989.86kg less than the vehicle’s GCM – well within specification. SUMMING UP By weighing the contents of the van and vehicle, I was able to determine that my rig for the Christmas break was legal on all fronts. The caravan was within ATM (with 209.86kg payload capacity spare) and well below the the tow vehicle’s 3000kg towing capacity. The loaded weight of the tow vehicle was a little close for comfort but still legal, and the ball weight of the van was well below the vehicle’s 300kg towbar maximum. When laden, the van imposed 200kg onto the tow vehicle's towbar. The combined weight of both loaded vehicles, meanwhile, was comfortably within the MU-X’s GCM. Finally, I recognise that weighing payload individually is not ideal as it leaves room for error. Also, bathroom scales typically weigh items to the nearest 10 grams, so it’s possible that my figures are a little out of whack, but not so much as to invalidate the exercise. I always recommend taking a loaded rig to the nearest weigh station for the most accurate figures; however, for some travellers, the simple act of getting there could be illegal. Whipping out the bathroom scales and weighing everything individually will give you a close measurement of your rig’s weight, and might even encourage you to leave some of that heavy gear behind. Furthermore, it wasn’t particularly time consuming – I encourage all vanners to give it a go. I think you’ll find it very enlightening. / 23
