Squeaky floor on my Bailey Ranger

Swifty 123

Just been down to France for a 3 week trip and had a brilliant time and the weather was red hot, as the hols went on we began to notice that the floor of our Bailey Ranger 540/2 of 2007 vintage developed a quite noisy squeak when walked upon!   We have never
noticed this before and wondered if it could be something to do with the very high temperatures we had whilst away, still squeaking now but not quite as bad, wondered if any of you Guys & Gals out there had any thoughts on this prob? Don't want to annoy my
neighbours on CC sites now I'm home !!!!
