If you haven't looked yet do what Dunner said. Check out the CHF or Cheap Handling Fix. It's 107 pages long, over 1,000 posts and I read them all. It has worked for many, many F-53 MH owners.
Now some information. Shocks are designed to absorb the energy stored in a spring when it hits a bump. Basic law of physics, "Energy can be neither created nor destroyed but changed from one form to another." The energy in a spring will either dissipate by continuing to bounce or oscillate or it is turned into heat by a shock. That's it and nothing more. When wind hits the side of the MH the body tilts and the shock resists some of that movement but not all because it is side to side movement. Anti-sway bars, or torsion bars usually one on front and one on the rear are attached to the body by links. They are torsion bars which are basically long springs. They resist body sway or side to side movement from all kinds of wind and road dips that tilt the coach from side to side.
There are three axis of frame movement: vertical or bouncing up and down, horizontal or tilting of the coach side to side and the frame twisting left and right like you were on top of the roof looking down. It's also referred to as the tail wagging the dog. Shocks resist movement in the vertical direction. Torsion or anti-sway bars resist motion from the horizontal direction and Trac bars are designed to resist frame wagging. An airplane will yawl, crab or side slip coming in for a cross wind landing. That's frame twisting.
There are many different designs of shocks. I thought Bilstein and Koni were the best but some have spent the $$$ and they were not satisfied. Air bags will help as many have said. I know the CHF will help with the sway. Read the CHF and you'll learn a bunch.
