John, don't have a Citation 24sr. Do have View Profile which has a similar dual slide arrangement and floor plan. Does not have cab over bunk. You will like the sliding queen as you can get in and out without disturbing your mate...and it is semi-walk around. Also, the push out gives more room in the "day room." You will like that! Couple things to consider.... The galley is right inside the door and there's no counter space...which is kind of handy for workspace or setting "stuff." The 36" TV on the Citation is on the wall next to the setter. That may be hard to view when sitting on the sofa. Although its great if the driver and passenger seats spin around to face the lounge. You may want to check the ease of access to the cab with the over cab head board in place....especially if you have it set up and want to use the lounge.
My suggestion is to look at a couple floor plans and "block out" (like a stage play) how you would use it and live in it. See it the layout works for your lifestyle.
We had a '10 Thor Four Winds Ventura class B for three years. On the whole it was pretty well assembled and quality parts and bits. That said... Thor appears to have QA/QC issues and some of their product have many issues in abundance. Like buying a horse...ride it...check every thing to see that it works....have it vetted....
