The DE is not "in charge" of program, or shouldn't be - that should be up to the volunteers who should plan the camporee. In my experience, the DE is "more concerned" about fund raising and, IMO, should be.
When your DE steps in to the program area, it is easy for the money to distract them and you, as a volunteer, can easily get frustrated. Until I worked with several DEs on a council-wide event, I had mistakenly believed that they were there for program (like I was). I learned my lesson on that one.
I believe the district volunteers should take the lead for district events. Use the DE as a resource. This can help avoid the problems that arise when "being on the same team but with varying goals" occurs.
