There is so much written within the post that is exactly the opposite experience of a huge percentage of Heartland owners. I acknowledge that there are Heartland owners that are unhappy with their purchase. Some have told their stories here. Almost universally, there is a story within the story...and as earlier mentioned, a poor dealership service attitude has been revealed.
Heartland's customer service at the factory has a fantastic reputation for helping owners with quality issues when they are actually made aware of the problem. When a quality issue is brought to their attention, they will get involved...but it does help if the customer approaches the problem with a goal of getting it resolved and not just tearing into the customer service representative. Heartland has a history of allowing an owner to take their unit to "any" rv dealership the customer pleases to get warranty work completed...the dealership does not need to be a Heartland dealer...all Heartland requires is the dealership to discuss repairs with them before continuing...
The Op needs to contact the Heartland Service Department...The phone number is prominently displayed inside the coach...they will help if there is not a "rest of the story"...
