Sprinter Fresh Water Siphon Leak

This has been touched on previously however, I would like to pick-up where it last left off. Our 2013 (Sprinter) Free Spirit SS has exceeded expectations, with one minor exception. I fill the fresh water tank to 100% just before it hits the overflow. When I head out, down our somewhat steep driveway, there is a trail of water.

This is the result of the overflow tube being too low. I have confirmed this design flaw with Willy at Triple E in Canada, as well as a few LTV dealers. Here's the rub, I'm getting mixed signals on the fix. One of the service managers at a certified LTV dealer said, "put an extension on the overflow tube and route it up above the tank.

Willy, from the factory doesn't like this approach as he feels I may create a P Trap. He feels that I should remove some of the insulation around the hose, try to get to the top and create a new drain above. This approach is darn near impossible as getting to the top of the overflow tube is more than difficult.

As the conversation ensued, Willy reassessed his concerns about the P Trap and suggested I might want to give the easier approach a try. He was concerned that the tank could collapse from the P Trap dynamic. He then felt that the tanks design (long and thin) could withstand this given its configuration.

Bottom line, I hate unintended consequences! As such, I want to "measure twice" on this fix before I move forward. I'm hoping that there are some pearls of wisdom out there to give me some direction.

Thanks in advance...
