Holding tank Question
Both the gray and black tanks in my '78 Minuet 6.0 Metre are plastic, and the above floor mounting method utilized wood wedges to secure the tanks in place on the floor - - so far as I have been able to determine, there were never any metal straps used to secure the tanks (it is possible that there might be strapping on the extreme ends of the black tank as it has never been completely removed since I purchased the trailer - - just exposed to repair some leaks).
