Leave the emergency(parking) brake off?

As for the 'rolling the dice' comment, it's much more likely for them to stick in the on position as releasing is just the removing of the engagement pressure as opposed to the pretty strong force you can apply with your foot to engage them. If their condition has deteriorated to the point of seizing up, they will do so the first time you normally step on the brake. All that retracts disk pads is what little axial runout exists in the rotor. Not like old drum brakes with strong retraction springs. The best thing of course is to just get out RVing on a regular basis. That's what you bought the thing for! I always set mine as I know I'll be heading out in a week or two even if just for an overnight camp in my 'portable fort'! I've also been a mechanic all my life and have always thought changing brake fluid every 5 years or so was a good idea. Ford's 2 year interval seems a little overkill but, hey, they have the engineers. If I changed the fluid in my 2 year old Winne, I suspect it would still look like new. I lived in Florida most of my life and was always concerned about moisture getting absorbed into the fluid. Standard brake fluid was designed to absorb water so it would be distributed throughout the system to prevent it from concentrating in one spot to attack the metal parts. Each time I would change the fluid (pretty easy to do and if done right, far simpler than actually bleeding air out), what came out was dark and nasty looking. I'd continue to run the fluid through until it was coming out new looking. Once I got in that habit, I found I rarely had to change wheel cylinders or calipers anymore.
