Let me preface this by saying I just got it last night, so the simple answer may be the correct one. It is a 2011 33QB, I got it home last night and did the typical "flip all the switches" to see what they do. The rear box labled "Rear Jacks" I opened and used the toggle to go up and down, no movement or noise. I checked the fuses and nothing blown (from what I can tell). Not sure what I am doing wrong...I dont need them right now, but I would like them to be functional for our first trip in a week. I figured its best to trip now, than 300 miles from home
