We tow our 155 XL with a Jeep Grand Cherokee Diesel.  It tows like a breeze but in occasion when it's really windy or when I forget its back there ( remember the diesel goes like hell) the trailer sways a bit.
Been looking at sway bar systems... any specific models or manufacturers that fellow members can suggest would be appreciated. I've found a couple reasonably priced <$200 both online and at Harbor Freight.

Before you buy something, make sure the weight distribution is right. 10-15% of the trailer weight should be on the tongue (hitch). Getting more stability may be a simple matter of packing the camper so more weight is forward.

Very important point.

 Also, don't make money a factor. Research and get the best one. This is a safety factor. 
Of it fails for some reason, you'll regret not getting the highest quality.

Thats good advice. Tongue weight is very important. That said, if you have tongue weight right and still have some sway, a sway bar may be the right answer. They’re not a complex thing, just a set of brakes to dampen the swiveling of the trailer. I use the Harbor freight version on my 199FKS, works fine, a little chattering on slow, sharp turns but not a problem over 3 mph.

we have 195 that we purchased last summer.   before the commitment to a camper trailer we rented one for a long weekend as a test and reality check.  we pull with a ram 1500 diesel.  that truck has good relative fuel economy and lots of torque starting at low rpms, so a good tow vehicle for this trailer size and load range.  that truck uses coil springs which makes for a nice ride when not towing but with the tongue weight of a mid size camper trailer these sag down.  pulling that rental trailer was not a comfortable experience and we did not have all that far to go!   when we bought the retro i knew i needed to do something as regards stability, so i made two upgrades:

1) added air suspension to the truck rear wheels using a product from https://www.airliftcompany.com/   i got the 5000 lb version with an internal jounce bumper.   i did not bother to get load leveling which involves the capability to put different pressures on each side.  the compressor is under the back seat of crew cab and there is small gauge with little fill and empty buttons on the face attached a bit to the right of drivers legs under dash.   i had this professionally installed. 

this has been a very good product and it really firms up the rear of my truck for all kinds of loads.  having good strong suspension is important aspect to overall stability when using a weight distribution system as per below.

2) purchased and installed a reese straight line trunnion style weight distribution system with cam sway control.   i purchased the 66083 product which is for 800 lbs tongue weight and includes the hitch shank.  http://www.reeseprod.com/products/weight-distribution/strait-line/weight-distributing-kit-sway-control/xihofqeC8HIVQN7yFHYCaNzLo0SgomgD  i installed this myself but i like to do that kind of thing and have all the tools i needed.  

this product has been fantastic.  i did a ton of research before i bought this product.  i choose the trunnion style with the cam sway control because this had good reviews from others, and this seems a superior way to go for controlling sway.   some sway systems use a friction resistance brake and sometimes the resistance device is on both sides but sometimes just on the one.  these braking style systems serve to slow or resist sway as it begins to take place.  supposedly, the cam system holds the trunnion bars in the centered position, resists movement away from center, and helps re-center the position.   the claim is that this approach is more active to inhibit sway.  once you get the hang of it the hitching and unhitching is really quite quick.   i have heard that some systems can introduce some difficulties when reversing while making tighter turns (like backing into your camp site) and that some have to be disconnected prior.  i have experienced no such issues and seem to be able to reverse pretty much as i was able to without the system.  

the difference towing the camper trailer without and then with the two upgrades noted is like night and day.  the towing stability now feels rock solid.  the trailer tracks so steady and clean both while going straight but as well in corners.  it just feels married to the truck.  when passing or being passed by huge transport trucks the turbulence is hardly felt.  same with cross winds.  we live in ontario canada and last fall drove down to the florida keys and back.  these stability systems were great for us.  the boost to our comfort and confidence while driving is worth every penny.  i would never tow a camper trailer without these now.  i highly recommend both.
