So sorry to hear you're having these problems. I, too, was thinking about the Lemon Law. If you haven't already done so, I'd be inclined to send a detailed letter with copies of all your "repair" paperwork directly to the manufacturer...certified mail, return receipt. You should not be having this with a new TT and they need to make it right. If it means replacing the unit, so be it. If they say to return to the factory for total refurb, they need to compensate you for travel time and lost use time. I'd be on them on a regular basis....politely and respectfully, but REGULARLY. How proactive is your dealer? They need to come up with some sort of resolution so you don't end up paying for months for a trailer you can't even use because it's in their shop. IMHO, you need to be respectfully disgruntled and let them all know it.
