We used to have this as an option but it was not ordered very often. When we offered it, it was the Lippert version. I've had it and I've had (still do), the Mor/ryde version. Being totally honest, I prefer the Mor/ryde, though it's been many years since I've seen a Lippert model.
To roll out both sides, carefully measure the clear width you have on the off-door-side between the UDC wall and the gen wall. In my case, I CANNOT roll a 36' width tray out the ODS. If it was critical to me to be able to roll it out both sides, I would order the 33" width tray.
