Nope, never personally had issues with the fenders. However, once a screw strips out, it must be replaced with a more substantial fastener. The underlying material has been compromised.
Once the RV is level enough for the fridge to work properly, all drains should work fine. If you've got gaps where they don't belong, get things repaired, replaced or use LOTS of silicone sealant!
