We have a corner bed in our Phoenix Cruiser and find it well worth any hassle. There are only so many ways you can lay out a small motorhome and this arrangement simply allows for more room elsewhere.
Is it idea? No. Is crawling up a ladder to a bed less than 24 inches from the ceiling above the cab a better solution? Not for us. Is it better than a couch that makes into a bed, therefore requiring in most instances the stowing of the bedding daily and then flipping it out again to stretch out or take a nap? Not for us.
I just don't think for a single person a corner bed would be much of a hassle at all. For two people like us, one obviously has to crawl out over the other person to an extent for night to visits elsewhere. This is not as a big of a problem as some seem to suggest and it would a problem for a large person or an infirmed person.
We have had the couch conversion on another two rigs and find the corner bed works better for us. To each his own and his own style of traveling and comfort.
