Hi, my husband and I just purchased a 2010 Landmark Oakmont. We asked the dealer to install a 2nd AC unit in the bedroom (which they did). However, I cannot locate a user's manual in all of our paperwork from the dealer. There is simply a 2 page "Limited Warranty" page that they handed us just as we were leaving the parking lot. Other than it saying "Dometic" on it, I cannot find anywhere on the unit (on the inside) the model number, serial number, etc. so we can register it. Does anyone know where to look for this?
