Just put the stabilizer jacks down. Since you mentioned a TT, most are scissor jacks and rated at around 5000 lbs. I've had to do this myself once for an emergency CG repair and I've also used them to support the entire TT when I repack wheel bearings.
I would not recommend using the stab jacks to support the entire length of the trailer for support with the wheels off the ground. I would be concerned that the trailer frame is designed to support spans from the wheels to each end (front or back) and supporting the weight of the trailer at the ends of the frame would "tweak" the frame. This is the same as using the stab jacks to "level" the trailer which I think is a universal NO-NO. To use them to support the front end to put on say the tongue jack should be O.K. from the frame standpoint since this is not much different that supporting the from of the trailer normally with just the tongue jack.
For lifting the wheels I would recommend using a jack
1. between the axles on the frame ... my preferred method using a 12T bottle jack. A thick 4 or 5" long steel plate between the lower frame webbing and the bottle jack would be good to spread the load more equally along the frame at the lift point.
2. On the frame as close to the front or rear axle as possible
3. On the axle itself within say 6" of the existing axle support and only if you are using a "curved saddle" on the jack that matches up with the axle shape.
I'm also not a big fan of using these "ramps" under one tire to get the other tire off the ground since especially for the "tor-flex" type axles you are "SERIOUSLY" overloading the axle whose tire remains on the ground. I haven't heard or seen any damage from this, but IMO it's just a poor practice to do this.
