Hot water heater pipe was loose, dripping in a place not visible. Was not known until major subfloor damage was done. Have been calling GD for over a week leaving multiple messages a day and have received NO phone call back. Can not get ahold of anyone. Trailer is only 1 year old and barely used. Trailer has been sitting at dealer repair shop for over 2 weeks, unusable. Dealer repairs for labor only were quoted at 200 hrs at $140/hr for $28,000 without materials. Almost $30k in labor (afraid to find out materials cost) to repair a trailer that was purchased for $40k. WORST RV experience of my life and will NEVER purchase a Grand Design and not recommend them.
