We've just taken delivery of a new Esprit T 7090, but last years model. A couple things that I'm curious about, the first being the bathroom at the rear has a window, but no blind or screen. I'm not wanting to give fellow travellers a shock, but I find it a bit strange that there is nothing there. Is it missing, or is it that Dethleffs don't think it's necessary? Secondly, I note that the switch operating the Thule step has a blank plate, which when removed, reveals two taped off wires. This is at the side of the 'stairwell'. Would anybody be able to tell me what was there? I'd like to have an idea, before I ask the dealer. Thanks
