I am really sorry about the OP's experience with his new Redwood. I cannot even imagine the frustration level with those kind of problems.
As a Redwood owner, these stories (and I have heard them)boggle my mind. We have had exactly the opposite experience. Our 2013 36FB has been almost perfect. We have had it into the dealer a couple of times for relatively minor problems with the biggest one caused by the dealer (wrong batteries installed). The factory has been most accommodating on the phone and in person (we have been to the factory for visits twice).
We have been very pleased with our decision to buy the Redwood. IUOE150, I wish you the best in your attempts to get it resolved so you might be as pleased in the future as we are now.
