Not having to move the bed, added storage was the reason we said NO to mr. Murphy.
That said, my wife & I have developed a strong dislike of our bed east west configuration. Night time potty calls are a Major PITA with both people being awake for one to go. Since I removed the upper bunk and replaced the lower bunk mattress, I was happy to sleep in it when my granddaughter wanted to sleep with meme the only time we camped during covidarama. More roomy than my sub bunk in an officer’s stateroom.
It was Murphy or east-west bed for the BH trailer chosen to be towable with our Explorer. I’ve now paid the TT off and bought an F150 but after all the modifications I’ve done to the TT, I want pay down the truck before buying a new larger trailer. And if I ever do buy another TT, the grandkids will not play as important a part in choosing.
