I bought a brand new 2019 Landmark 365 Newport in june 2019. This has been the worst RV I have ever purchased. Right off the bat the vacuum breakers leaked and rotted out my front compartment floor. Within the first year the Dining slide began to leak and rotted out the slide wall. within the second year the other slides began to leak. All the slide seals plus repairing water damage is going cost around 20K.
