Just discovered this on our Vantage 32FLS and thought I would post to alert others to check theirs for the problem.
The 32FLS has the kitchen on the slideout. As a result, they used a flexible line on the drain line from the kitchen sink (flexible plumbing line is 1.5" Uniloop Drain Hose Assembly manufactured by Flexaust). The problem, the flexible line is 2 inches too short, causing strain on the connection under the fridge/trashcan area, which results in a leak!
And, of course this was discovered right after getting it back from dealership for other warranty work
To check yours: there is a panel below trash can drawer that has two visible screws holding it in place. Remove those, run water in sink and check for drips where the flexible hose connects to the rigid drain line.
Hopefully this is an isolated incident rather than one affecting all of the 32FLS units.
