we recently purchased a hymer B588 2016 and have been on our first trip. Whilst away we noticed water had got in to the garage floor and the battery compartment. After checking for any internal leaks ,, where we found none.. and reading on this forum. we have noticed others have had the same problem and shows the rear nearside wheel arch has a flaw ... after spraying into the wheel arch , water proceeded to flow onto the lower floor. Has anyone got any advice on how to solve this problem. We purchased privately.. Also we have read that this is a manufacturing fault and knowone seems to want to cover this under any warranty. Surely this should be a recall. Any help and suggestions would be much appreciated.
