Should have the same rating as the sport which I think is 4k MT and 4.5k AT. Should be printed out on the door sticker I believe.
Not much of a tow guy myself, not sure what other weights might effect with payload included with tow weight, etc... sure someone will chime in with experience.
Adding a trailer brake controller seems to be helpful. Payload for the AT sport is around 1k so possibly pushing it with weight. Think MT sport is 1.8k Payload.
speaking only to the rating: Did you get the tow package? Assuming automatic transmission...
it would have the hitch, larger alternator and fan/motor (cooling)
the easy visual tell is the hitch.
If without the tow group I think the tow rating is 4000 +\- (willys is classed as a sport)
So Even without you should be fine, but at the rated upper limits; just be sure to watch the load / loaded weight, all the stuff.
If/ With the tow you should be rated at 6,000lbs towing, but watch the tung weight and trailer brakes and controller should probably be in the consideration. The ole “informal” rules I learned years ago were the weight of the tow vehicle, limited the weight of what you’d pull without trailer brakes.
there are some threads on here, I asked this too back when I bought my Willys, I’ll see if I can find that thread and link... in my digging this site/these fine people are the best/better sources of otherwise hard to find info: “Tow Ratings.... clear as mud”
Is that really what the camper weighs? ie have you loaded it up with all your stuff, and scaled it at a CAT scale?
If not, do that then re look at it. IF that's the weight on the sticker of the trailer, see above, if that's what the dealer says it weighs, see above.
If you weighed it then you're more than good to go; breaks and a WD hitch would be my .02$
Dry ok, what's the water capacity, water is 8 pounds per gal (ish), 35 gal is 280 pounds. Propane bottles are 55 each full for the typical RV size 2x is 110. Batteries? one is 60 two is 120.
That's 510 before you have even loaded a t-shirt. Unit have AC? awning? That's usually an accessories item and not counted to dry weight.
What's the GVWR of the trailer? That's the number you need to work off.
Stuff: case of water, case of beer, BBQ grill, ice, cooler, food, clothes, bedding, chairs etc?
I bet your "stuff" will be close to 750lbs if you actually start thinking about it. That's in addition to the 510 above.
Too many get locked into the "dry weight" of the trailer and run with that vs the maxed out gvwr of said trailer. Work off than then see where you are/will be.
I'm trying to be helpful, not a downer. Sorry if it seems that way, I'm doing this same exercise on the rig I want.
Mine is a small 16' toy hauler, that I'm sacrificing space and amenities for in order to have tow-ability. I'm looking at apx 4700 ready for the road weight + my gear/food/generator of apx 750k + 800 in toy weight = 6250.
You can leave it in drive and go where you want with no need to go into "manual" mode. The trans will adjust shift points for you and adapt. If that is annoying to you than "manual mode" is fine also.
-Single axle trailer might sway a bit so "antisway" hitch would be good.
-Trailer brake controller should be add for your safety. Based primarily on the fact that you are asking about towing.
-Tongue weight matters. Be around 10% Better too much than not enough. Better to squat a little vs fish tailing all over the road.
I guess that tow ratings guide is all we have to go by. The Willys doesn't have the exact same suspension as the Sport S but should be at least as good towing.
