I carry the standard Trailer Aid and a 12t bottle jack plus the normal 4-way wrench, large size, not stubby. On my last trailer with the Trail-Air suspension the standard Trailer Aid would just barely get the back tire off the ground. Were I to buy again I would get the taller version. I tried the 6t jack and it just didn't like the weight. (Wally World Special)
I haven't tried on my new trailer, may I never have to.
