My question is: Could it be that the Four Winds Citation - 26BE's wheelbase length is the culprit?
Example: The wheelbase on my rig is 171" and the total length is 27'4". The wheelbase of a shorter rig... the 24BB is 197" with a length of 26'5".
I doubt that your wheelbase is the issue.
My E450 24 foot Itasca has only a 158 inch wheelbase and it handles and steers just fine - stock, right from the factory.
As I'm sure has been covered in this thread's many pages already, the problem most likely could be the portion of your rig's weight on the rear wheels as compared to the portion of your rig's weight on the front wheels, plus maybe -> the front end alignment not being set right so as to deal with the portion of your rig's weight that is winding up on the front wheels.
Just as a datapoint, my E450 Ford chassis came stock with anti-sway bars on both the front and rear and stock with a front steering stabilizer shock absorber. I'm sure these two features help with handling and I'm not sure that all E450's come with both of these.
