NickG, I understand exactly what you're saying. My previous trailer was a Jayco 28bhs with manual scissor jacks at each corner. My current trailer is a Vibe 308bhs with electric jacks just like yours. I've done all of the suggestions posted here to both campers except I've never tried the JT Strongarms. The old camper was almost completely stable. The new camper shakes so much that a kid rolling over in bed wakes me up just like you describe. I'm ready to ditch these sorry electric jacks and add manual scissor jacks to the corners like my old camper. Hand cranking those manual jacks never bothered me.
