Re shock absorbers. I think Bilstiens or Konis for RV use but seriously I think some put rubber around the opening or make a shelf with rubber for the AC to sit on. Low watt ACs are only around a hundred bucks so maybe it doesn't matter to you.like you. I bought my lil B to use without having to take the Bounder out and feel much more freedom. I am also trying to weane the wife away from the bigger rig for when we ritire and travel more. Thanks for your posts.
