The cyclone weather earlier this year in the Cairns area has caused much water damage to my Jayco Starcraft.  It is not insured.

I need to repair the floor in the toilet area and think that the best way of doing this is to open the rear end of the caravan to remove everything

up to the fridge.  That way I'd be able to replace part of the floor, which has gone a little soft. Does anyone know how to remove the

very rear panels of my caravan?  Perhaps a link to a video would be great.

It would be easier to remove fitments in bathroom/ensuite then cut out floor with reciprocating saw, ensuring that plumbing under floor isn't cut.

When fitments removed drill from beneath van beside chassis members, then recip to join holes, you may need to scrape off any floor material that is affixed to chassis with adhesive.
Replace floor section with marine ply and refit fitments.
