Thanks for the input...I was just curious! Our new BC has cables for the bedroom, something I am not very familiar with. It seems some Bighorns do and others don't! I wonder what the deciding factor for using the cables vs hydraulic in the design is. I know a cable system must be cheaper. I also think it must take up less room under the bed. Our BC has a good sized storage area under the bed...not sure this would be possible with hydraulic rails etc.
Happy Camping!
