Which model Safari do you have? 3530? From the photos, the front half layout looks much like my 3540, except my door is in front.
I also have the Elipti-ride, leaf springs – simple and effective. The Velvet Ride is the torsilastic suspension – something to stay clear of – Magnum Chassis did not do that one well.
Mine has the Pacbrake exhaust brake, which will do 90% or 95% of the braking. I assume yours does, too, and the air pump and reservoir will be mainly for that, plus it will power the air horns.
If you take out the sofa and the one existing recliner, I think you will have room for two recliners on the driver side and a not-too-deep cabinet for a TV on the passenger side. I think the recliner plus sofa makes things a little crowded in mine. As stated earlier, I may swap the recliner for something more compact.
