Saw the Melbourne at a RV show. I'd say it is about equal to Forest River's Solera or around that tier. It was decently comfortable inside.
The one notable thing it had, and I really wish all Sprinter class "C"s would do this... it had a diesel generator. The LP gas ones are very thirsty, and here in Texas where you need to have the A/C going, generator run time is a must.
