Standard of Australian Caravan Manufacture

Good morning all
A few weeks ago I scratched the side of my caravan $2500 worth 10 side panels and a new window required. Watching what someone else was doing and not concentrating on what I was doing. My fault entirely.
Yesterday the repairer called me and asked me to come to the workshop as he had found a major problem. The caravan manufacturer (who has since sold out and the new owners now build them in WA) had installed the 3 way refrigerator without drilling a hole in the floor to let out excess water from it. Result the overflow pipe was just left to let the water onto the wooden floor. EXCESSIVE DRY ROT.
Is it possible that many Australian made caravans have the same fault?
My van was manufactured in July 2007 so my chances of getting the new owner of the brand to rectify a major "FAULT IN MANUFACTURE" is remote. But I will try, hence not naming the van make.
To rectify the problem I have three choices:
1. Rebuild the van from chassis up to replace the floor. Mega dollars to do that.
2. Cover up the problem and sell the van as suggested by the repairer.
3. Cover up the problem, drill a hole for the overflow hose. Continue to live & travel in the van until the van expires. All the time knowing my original investment of $72000.00 is devaluing at a massive rate.
Have you checked your van to find out whether there is a drain hole for your refrigerator? Probably not!
Stay well and stay safe
