Also it appears your chains are not vertical. This may have been caused by some slippage of your large u-bolt brackets thereby causing the cams to not be centered properly & thereby causing your sway issues. I have same system with the older style large u-bolts & I have to occasionally adjust do to slight slippage. After getting your cams centered, try to get chains as close to vertical as possible by adjusting lift-up brackets. Your propane tanks may be in way & some off-centeredness is OK. Others may know how much deflection is OK.
