yea 'change and put work into making another item' is a pain. a lot of rv'ers who have kids and want them to sleep in the 'dinnette' means changing the set up a lot....stinks and they sell and buy a bunkhouse floorplan LOL
best is have it easy. Like in murphy bed style. down comes the whole bed. done. up goes the whole bed, done.
so if the bed folds and is not used for other things and gives space, then yes they are great.....if they are required for other things then nope, just a pain ya have to deal with.
