Help on sway control and hitch

We purchased our 177 nearly 3 years ago and brought it home in March during a snowstorm; no problem with sway, even though we had a fair amount of wind traveling across the U.P. of Michigan.
The first 'shakedown trip" was another experience however.  Once we got above 45 MPH we got a massive amount of sway with about a 10-15mph crosswind.  We opted to spend the big bucks, about $ 85.00 and got a sway bar for our Explorer; problem solved, never had an issue since that was installed.  Maybe for some of you big boys with the longer wheelbase this is not necessary, but for those of us with smaller TV's and shorter wheelbases, this is a must in my opinion.

You had mentioned a bracket that had to be welded on to the tongue.  Mine is attached with 6 self-tapping screws which only require large pilot holes.

ok, still researching.  now i see what outbound means in regards to the weld on bracket!!!  just green in this area!!!   i see they sell shanks with the bracket on, but haven't seen one with a 4 inch drop, but i guess a good welder could do it right.   ok, now another question.  if your only using one bar, does it matter on which side  you put it on?  etrailer and the hitch store have a curt bar for $46.  any thoughts.  thanks for everyone's input, hogone

trying to research before i ask, but i guess i'm not finding what i'm looking for.  so it appears a sway/friction bar attaches to the camper with bolts/screws and to the tv on the shank on a small ball.  do i need to get a new shank for this or is there an adapter?  jloftin 60, you posted a picture of one that seems of interest to me.  where is that from?  i didn't see it on etrailer.  appreciate any info.  also, do these need to be disconnected when backing, making sharp turns whether going forward or backing?  hogone

Weight distribution hitch. A hitch that transfers some of the weight off of the rear of the TV and into the front wheels of the TV and the trailer axle.
