I have finally taken the plunge and purchased a MoHo after 50 years towing a variety of wobble boxes. Only collected it yesterday and had a rather damp misty journey back from the (excellent) dealers near Ross on Wye and when I came to reverse into the garage I couldn't see through the rear view camera - later realised it had been obscured by road dirt sucked up in the vortex at the back. Apart from hopping out to clean it (with a sponge on a long pole ?) have any funsters a helpful solution to keep it clean in murky conditions ? The van is a Bailey Compact 540 by the way.
