Domani owner here. We bought our 2008 DF300 a year ago. Due to circumstances the 7 year old trailer had never been slept in. Most of my problems I had to deal with were shakedown problems that should have been fixed under warranty. As a result, I have become pretty familiar with most of the systems on the trailer. I had to change the mount system for the two tables as stock was unworkable. Built cushion extenders for the rear couch so that it sleep worthy. Installed slide toppers. Installed Yamaha sound bar. I have a row of 4 switches by the door; rear sconce, light above door, right front outdoor light, left front outdoor light.
I know the Domani community is small for these beautiful trailers. Feel free to PM to share.
