My '01 Safari was 5,500 lbs unloaded. Without water but with my normal food & clothing load, it came in at 6,000 lbs. Hitch weight was about 730 lbs. GVWR was 7,300 lbs.
Interiors on the 27' model were all front sofa, folding table on the street side. Mid bathroom with shower. Across from the bath was a large double door closet.
Rear options were two. Either a queen bed or 2 twins. Let me know if you have further questions.
