There has been some discussion on CT recently about the sealing strips between the caravan body and the lower panels front and rear.
I know this is not a waterproof joint as the lower panels are to a certain extent sacrificial in the event of damage occuring.
The strips are not very successful and to be honest look a bit of a mess at the best of times.
Some chap said he had removed them and things looked much better for it.
Before contemplating this route I wondered if anyone had some photos with them removed so I could see what it looked like.
