Bill- I have a 2017 Isata 3 RW as well. No cab over bunk, no diesel gen, no levelers. However, my CCC is only listed at 810, while I saw you post yours was 943. Any ideas why the lower CCC on my rig? I do know mine was a Jan 17 model and is has a spare tire. Have you been overweight much and if so, has it caused any problems?
