I have had all three of the common stabilizer jacks. (A) the kind you fold down and put a bar in for adjustment. (B) The single arm crank down jack (C ) The scissor jack Not on the list are jack stands. A) you have to reach under a pull down and adjusts ..... maybe light duty only one mounting point. B) you will need jack pads, but you just crank them down ....... has a long rail that mounts to the trailer and the lifting arms are at an angle (does that make a wider stance?). The pads add a nice contact point? C) Just crank them down. Seems to me sometimes they hang down lower of the trailer when traveling. Jack stands are sturdy , who wants to lay on the ground. Every one has it's faults and the trailers wheels need to cocked to prevent the trailer from moving with all of them. What do you guys and gals think is better and why? I replaced my (b) type jacks (mainly because they didn't have a socket end) with C) scissor jacks but I think the scissor jacks hang lower, smaller pad to the ground and have a wobble to them. So I don't know what's better.
