Cyclone 4000 Elite vs Voltage 3970 for fulltiming?

I really like the 4000 floor plan. The 3970 looked even better at first. What I think it comes down to is larger couch and black tank in the 4000 vs more kitchen storage in the 3970. Both garages measure about the same. From reading the dutchmen forum it looks like voltage dropped the exterior radio controls and keyless entry.

I just can't see the smaller couch in the 3970 working for me. It looks like only two adults can sit comfortably. I really wanted to like the voltage.
