I have a 2009 BHDS 35.5' length. I have a problem stabilizing the unit on concrete and/or dirt. I use wood blocks if needed and make sure my jack are snug and firm. I have experienced extreme side to side movement. I can be laying in a bunk in the rear and when someone in the front BR turns over I can feel the unit rock. I also use wheel chock between the wheels on each side and that stops any forward or backward movement. Can't figure it out. Any comments
out there?
