What kind of jack do you carry with you in case of a flat tire on your trailer? I'm looking at a bottle jack that has a jack stand in one assembly. like this: Alltrade Tools 620470 Unijack Hydraulic J...

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.
You do realize, your axles likely see 10,000lb or more when they hit a pothole at 60mph.
Jacking is for practical purposes a static loading situation. The ratings are based on dynamic loading.
That said, we have a 3 ton floor jack and if it's squishy ground, the leveling planks can be put down to support it.
