Bought our brand new converted camper back in the Spring (having never owned one before and therefore having nothing to compare). I am trying to gauge whether the slight noises that my roof makes are 'normal' or need investigation. Silence when going in a straight line but when cornering (especially, say, a roundabout) I get a gentle creaking and/or knocking noise from overhead (first thought was that my brand new van had noisy top suspension mounts but realised it was not noisy enough and above me, not in front). The van has a Riemo pop top with factory fitted Active Rails and is held down by the standard two straps at the front edge of the roof. If I open the window and place my fingers across where the roof and pop top join, I can feel a tiny amount of side to side movement from the pop top. I wonder whether I am maybe hearing two rubber seals working against each other but as an Engineer I need to know! Anyone else have similar or can simply tell me that this fairly normal from a pop top roof?
