New RV problems

Recently we purchased a 2015 Keystone Bullet 24RKS travel trailer. The toilet was installed too close to the wall so the toilet lid does not stay up. Very inconvenient! Took trailer in to local Keystone Service Dealer 2 months after we purchased it to have this issue fixed. We were told by the dealer that Keystone said this was a design issue and they would not fix it. I phoned Keystone directly and was told the same, they would not fix this problem. All it would take is to move the toilet 1/2 to 1 inch from the wall so the lid would stay up when using toilet. Just a warning to all who are interested in a Keystone manufactured RV, they are not interested in customer service and satisfaction.
