Just dont forget 'Size isn't Everything'.
Ive seen lots of CCs vans with absolutely loads of equipment, TMs, chemicals tools etc in the back, and from what Ive seen, I can tell you most are not only overweight but massively overweight.
Now this is not a problem until PC Plod stops you or worst still you have an accident and if its your fault and someone gets hurt, they will throw the book at you. Ask Dave Ingram about when he simply got stopped, becuase his van looked heavy and they did him not once but once each for each of the three axles that were overweight.
I have a long wheel base, high roof Citroen Dispatch and this van has a 100kg more payload than almost any other van of the same size. There is a lot of room in the back in spite of there being a big TM fitted. However I am limited to what I can carry because of the weight issue. I only carry chemicals that I may need for the day, only 200ft hose (the rest stays in the garage) and with afull LPG tank, half a Diesel Tank and Half a Water tank, and just me in the front, I only just legal. If I then put the RX20 in or someone cadges a lift, I am over the weight limit.
Dave.
