We use the Euro chair constantly but we are full time. It is that favored recliner that most people have in their living rooms. We have a custom set up with cabinets and a flip up desk behind the passenger seat so space is even tighter than most but we wouldn't give it up.
The real question is whether it works for you and that depends on your use of the Phoenix. If you sit inside a decent amount -inclement weather, relaxing mornings with coffee, reading, evenings in front of the TV, the chair is awesome! If you run from point A to point B and spend your time in the driver seat, the bed, or out of the rig, you probably won't use it much. It is a very nice sitting spot IF you sit. If you load a bunch of gear or cargo, space for stuff may take precedence over comfy chair.
Being full time we probably spend more time inside than people on shorter trips. If it's wicked hot, evil cold, or swarming bugs, you'll find John either in that chair or propped up on his bed reading.
