Do the free stuff first, before you toss parts at it.
Check tire pressure. Preferably get axle weights and inflate to the recommended inflation from your tire manufacture charts. A good starting point for pressure is from the placard that that should be in your MH that states the tire inflation from Thor. DO NOT inflate tires to the maximum psi that is listed on the tire sidewall, UNLESS the inflation chart calls for it. NEVER inflate to a pressure higher than what is called for on the tire sidewall. ALWAYS use a cold tire pressure, and inflate each tire on an axle the same, even if you have different weights side-to-side, if one side is requiring more air, use the higher rating.
Here is a link to the Cheap Handling Fix, CHF.
https://www.irv2.com/forums/f23/cheap-handling-fix-72335.html There is enough reading in there for a week of bedtime stories. Look on YouTube for it too. It is not hard to do, you may need a small bottle jack or similar to get the bar lifted into position. An hour even if your old, slow and fat like me.
Pay very close attention to the rear sway bar bushings mounting. They are well known issue of bolts loosing off and falling out completely. Blue Loctite thread locker is your friend. Torque to 66#. If you need brackets they aren't real expensive from Ford. As said, check the bushings too. Ford used a soybean oil based product that self-destructed until the 2012 chassis model. Yours could be either. If the soft ones, replace with POLY ones. Lube with a liberal coating of silicon grease. There is/was a seller on e-Bay that makes quality ones, look for SkeeterDude
Some use extension downlinks in the front to keep the bar level but isn't really necessary. Make sure the bolts through the downlinks clear the springs. The change may cause your front tires to lift off the ground sooner when leveling, which seems to be the reason for using downlink extensions.
Trust me, the CHF is a profound difference first time, first turn out the driveway. I wanted more sway control and added a bigger front bar and the rear auxiliary one. Probably should have saved my $$ on the front one.
