Salem vs. Salem FSX - Difference?

[Sconner]

Looking to buy a Salem RV in Arizona and found the the FSX models are not available in the western US. Does anyone know why? What is the difference between Salem and Salem FSX?

Is it more or less insulation? Why is the FSX only sold in the eastern US?

I am looking at the 200RK (rear kitchen) and can only find it 1,500+ miles from my home in AZ. I would make the road trip for it...but would like to have more insight into the "FSX" model designation.

Any help would be appreciated.

Looking at the website, it appears that the FSX RV's are smaller than the standard Salem RV's. I'm not sure of anything else different about them.

Yes, I noticed that the FSX models were smaller. Maybe that's the only difference?

I took a pretty deep dive and could not find any feature / content differences between the FSX and non-FSX models.

I reasonably get how the RV industry works and this seems like a another marketing diversion to disorient the customer and protect dealer territories. Unfortunate but not surprising.
