The 179 is a great choice for a travel trailer but you really need to match it to a tow vehicle that can comfortably handle it.  The other vehicles you mentioned would work well, as would a Toyota 4Runner, provided they are properly equipped for towing a trailer of that weight.  It's best to have a margin of error on the towing capacity.  If you don't, you'll find that you're exceeding the combined gross vehicle weight, as was mentioned by offgrid.

Best of luck in your search.

Maybe a teardrop or a pop-up tent trailer.

Re your tow vehicle, all the ones you listed are on the small end of what I'd want to consider for towing a 179. I tow my 179 with a Highlander, which is slightly larger and heavier but in the same category. I consider it the smallest tow vehicle I would use. Luckily, it fits fine in my garage, but if it didn't I think I'd still squeeze it in rather than reduce my towing capabilities any further.

Size and weight matters while towing. Longer wheelbase, higher gross weight rating, larger fuel tank all help. For example, you will at best get around 13-14 mpg towing no matter what you get so a small gas tank might drive you crazy. The Highlander is just shy of 20 gallons and its OK for me but I wouldn't want it to be any less. You'll only want to consider AWD versions of any of those vehicles of course.  

How you camp and what you take with you is very important in making your choice. Are you going to be boondocking? If so, you will want to be able to fill your water tank and will probably want dual batteries. Together that adds a couple of hundred pounds to the tongue weight. I boondock and mine tongue weight is right at 500 lbs, which is generally the limit for vehicles this size. Add passengers or a bunch of heavy stuff in the back of the SUV and you're overloaded. It's just my wife and I and we carry just a few light things like folding chairs back there. I wouldn't add anything else or take any passengers while I'm towing. 

OTOH, if you're going to have water and hookups where you camp and there's just the two of you and you pack light and drive conservatively you should be fine. You will be surprised at how fast weight adds up though, get an actual weight on your trailer, tongue, and tow vehicle as loaded (you can use a public scale for that) so you know and aren't guessing. Trailers never weigh what the manufacturers say they do. 

One spec that is not generally published but important is the max combined gross vehicle weight. That's the max total weight of the combined rig.  You can't just add the 5000lb max tow rating to the gross weight rating of the SUV, that 5000 lbs is the max you can tow with only the driver and nothing else in the tow vehicle. The CGWVR should be listed (along with lots of other good stuff) on the driver's door jamb. 

Another consideration is that since you will be towing a relatively heavy trailer with a relatively light tow vehicle, you will want to have a weight distribution hitch to help move some of the hitch weight from the rear axle to the front axle of the SUV for better stability and control. So, confirm that what you get has at least a 500 lb hitch rating and check the manual and be sure that the manufacturer doesn't disallow use of a weight distribution hitch. 

None of these vehicles are going to be overpowered for towing but they won't be terrible either.  As long as you're not in a hurry you'll be fine on performance. Have fun!
