We have had two Dutchmen TT's, the second one being the same as yours.......the first one was a lemon in the extreme, and our experience with it being in the shop most of the time was the same as yours.
The day we drove it home, with the main door deadbolted, the door kept popping open. The first camping trip, we woke up to a soaking wet bedroom floor. Overall, we had 32 warranty claims in the first 8 months. The last straw was the front of the trailer beginning to warp so badly that it was almost separating from the rest of the trailer. This was also going to be a several thousand dollar repair for them.
We contacted Dutchmen directly, and simply asked a customer support guy to look at the service record of our first trailer. Between the dealer contribution, the factory contribution and a big discount on the 289RK, we got into the second TT for almost nothing. The dealer also paid us back what we paid for the first trailer on trade in.
We love our 289RK, although there have been a few warranty issue -- NOTHING -- like the first one, which was a nightmare.
I would suggest contacting the customer support line for Dutchmen manufacturing directly --- kicking it upstairs in other words. Start soft with them --- just ask them to look at the service record of your current trailer, ask them if this is what you should expect from Dutchmen, and ask them to suggest what you should do...really, that's all it took for us.
If your TT was made in Burley, Idaho, the contact phone number is
If yours was made in Goshen, Indiana, the phone number is
