I used to take small floor jacks but they are too old so I'm looking to get something just for the camper.

The truck has a jack that works on the trailer. I carry one jack for truck and trailer.
When I had a tandem axle trailer it was easier to just roll one axle side up on a rock or curb which made the other axle tire come off the ground. They only have 2-3 inches of travel, so not much lift is needed. Then changing the tire was easy, and actually safer than a jack.

Think this through a little. It doesn't matter if you are lifting 1 inch or 6 inches with the drive on type of jack. All of the weight is on one axle.
When you put a traditional type of jack under the flats axle you still have weight on the good tire's axle and weight on the jack under the bad tire's axle.
Example: 12,000 lb trailer, 2,400 on the hitch, 9,600 on two axles or 4,800 on each axle. 2 sides to each axle so 2,400 sitting on each tire.
Run one tire up onto a ramp it is holding the full weight of one side of the trailer or 4,800 lbs. Overloading that one tire.
Put a jack under the bad wheel's axle and lift and it is holding the 2,400 lbs for that axle while the good tire is still holding it's 2,400 lbs.
Which is really a moot point because when one tire is flat and or shredded, the other tire on that side is already overloaded and holding all the weight.
Going across a bridge jump will put more stress on all tires than you get when you lift 1 side with ramp under 1 wheel.
I use a ramp under the flat to lift most of the distance. It takes some force to work the jack when lifting. Just jack up to get the ramp out.

Your luck might be better than mine. If I'm out on the road I'm very likely to be missing a very important part needed for your new jack to work; A floor. That kind of jack, the lift plate goes up in a arc. This is not a issue, if, and only if the jack can roll. If of anything but a smooth hard surface, the lift plate is likely to slide, and drop the load. Even on a "brush finished" concrete driveway, you need to watch close as it goes up.
Very true. I use a piece of 3/4 plywood with a floor jack at home on the gravel driveway.

I've successfully tested and used my tow vehicle jack for my trailer. I'm not sure why it wouldn't work for others.

Used it many times at home, fortunately not on the road.

6 ton bottle jack. I won't use those trailer aids as they put all the weight of one side on one axle. A bottle jack only lifts the flat tire an inch or so and the other tire stays on the ground so that side of the trailer is supported by both axles.
I have 5200 lb axles. TT has 7850 lbs on the axles. 1/2 of 7850 is 3925.
1/2 of 5200 is 2600 lbs.
I'd be supporting 3925 lbs with 2600 lbs of axle using a trailer aid.
Another problem besides the axle is that all the weight on one side of the trailer would be supported by a single tire. You now doubled the weight on that tire. Another issue is if you have body damage from a blowout and turning the tire will cause more damage. I carry a 9 ton bottle Jack. It can be used for more than changing tires.

You have the tandom axel, get the trailor aid or just block up one wheel untill the other gets off the ground. . Your not moving so not really stressing the other side. If it was a problem they wouldn't make them. Carry a bottle jack as a back up.
I have read that the trailer aid does not work if you have the tandem leaf springs. I ended up buying the 3 ton jack from Amazon. it will be here on wednesday so hopefully it is a good jack. I leave on friday so if it doesn't work I'll just go to walmart and pick up a bottle jack for the trip.
