Had a serious problem with our RV. Engine would cut out without warning and no electrics, even when travellling at speed. Took it to a place at Trafford Park in Manchester today (Specialist auto electric workshop). Turned out to be a loose connection on the ECU. Took them a while to find it but charged me next to nothing to fix it. I have no commercial interest in this company but thought it would be helpful if anyone else in the North West needed to find a company well versed with motor homes/ RV's. I've now booked in to have a couple of solar panels and a new reversing camera fitted. They had an expensive 40ft RV/ horse box unit in the builing having work done so size is not an issue.
