...How do we get a refund?
What does your contract say? Every right you have is in the contract. If it isn't in the contract then it doesn't happen.
You did read the contract before signing, didn't you?
All your rights are not in the contract. The dealership writes contracts to protect them. Check with a lawyer, your banker, or a consumer advocate before making a decision prompted by the dealership. They are not your "buddies". They are in business to make money...period.
Finally a sensible answer. I get sick of hearing its always the consumers fault.
There should be a check valve on the pump to prevent this, it sounds like its defective, unless you have the valve setup that you can fill the FW tank off of the city water hook up, then the valves may be in the wrong postition.
Most delamination occurs due to water damage that causes the luan plywood to seperate. As I understand the new Adzal (sp?) are not subject to this because even if subject to water damage it does not have layers that seperate like luan.
Delamination can also occur when defective glue is used.
People like what they have so take what you hear on here with a grain of salt. Go to some campgrounds and talk to the owners. The statement made about 1 in 3 smooth sided trailers delaminating has not been what I have observed and we have visited every state in our RV.
