Here is a new cook book from the UK - may even work for VV's as well as camper vans & I did like the seagull alarm clock & here we could just use the Magpie Lark alarm, just put mirror foil (metalized window film) on the inside of one window & a windscreen wiper on the out side & the Lark will sit on the wiper & attack itself by beating on the window. Trouble is it will carry on all day.
