Sorry about all the issues with your Pinnacle.
We have been fulltiming in our 2011 Pinnacle 35LKTS a little over a month now and have had a few minor issues, but overall real happy with our purchase.
Water Heater stopped working on Electric worked fine on Gas, it was a bad Electric Operation Thermostat. (Attwood problem)
Problem with TV being snowy and not working on Digital Channels on Bedroom TV while operation on Park Cable. Installed signal booster, Bedroom TV is now crystal clear. (Assume problem is with park cable, worked fine at last park we were at)
We think the Fit and Finish on our Pinnacle is better than many other brand 5th Wheels in the same general price range that we saw at shows and dealer lots.
It is not perfect by any means, but we also realize it is a mass produced RV and the price point we looked at.
Overall not a bad 5th Wheel loaded with options for under 50K out the door.
