We have a tribute with a fixed rear bed across the back and a small step up to it. The bed is boxed in on 3 sides and just one partially open side to climb in. It has two single mattresses on it (no idea why when it is and can only ever be a double bed) and so we have a memory foam topper on top for comfort and because of the join down the centre. Ok now the biggie...how on earth do you put bedding on the bed. It took two of us over 30 minutes to put bedding on the bed, fighting trying to get the under sheet all nice and tightly tucked round the mattress which is impossible with two mattresses independent of each other, then you have to make sure the condensation sheet under the mattress lies flat and the memory foam topper does too I have only done one full bedding change and I am dreading the next!
