I think Boweld will build a Mucklight body if required. A close friend has one on Scania chassis for next month and two others were built about six months ago. This thread has been going on for some time is your gaffer going to make a decision soon ?
Six months ago? They must be starting to rust by now? 
TD, my boss has toyed with changing the 8w for the last two years. First time the trade in offer was crap, and our Izusu was on its’ last legs, so that was replaced. Next the 6w’ work died off so was sold off and replaced with a grab. Now my wagon is starting to cost a few quid but the work for it is picking up again.
