Autosleeper Kingham - what's gone wrong in 2 years of use? HD 1080p

We have now had the Kingham for 2 years and spent over 130 nights away, travelling over 8,000 miles. So what's gone wrong with it during that time? Inspiration for the film came from a comment by viewer Mark Mills, so thanks Mark for the suggestion.
