I think you might lose some ground clearance. I also think they look ugly. Maybe that's just me!

Why ??

They don't stabilize and more than what you already have, they also add weight to the rig, they look ugly on an Airstream, they lower the ground clearance, AND, they put a drain on your pocket book.

Even if you do buy free-standing scissor jacks, it's probably best if you don't use them to "jack" the trailer - just stabilize. Scissor jacks are quite a bit stronger than conventional Airstream stabilizers.

Experts here can confirm / deny, but as far as we understand it, those aren't jack points and actually lifting the trailer at these locations could create unfortunate frame-twisting results.

I would like to hear an expert response to the above. I have seen scissor jacks advertised in links from this site for use to level an AS. This would imply that there are suitable points to raise one side from without risking twisting the frame. I know the stabilizers are not intended to level. If this is safe a safe practice it would be great if someone could confirm this and advise where best to place the jacks. Thanks.

Honestly, the best location for leveling jacks on an Airstream is in the nearest dumpster. NEVER level an Airstream travel trailer using those jacks. EVER. For any reason. The list of Bad Things that will (not might) happen is too long to list here. First problem is tweaking the frame, which is not designed to carry the weight of the entire trailer in a single concentrated point, second, little things, like the main door not opening or closing when jacked up, and many times after the jacks being lowered. The list goes on.

Lifting jacks are almost always a hydraulic type of jack.

Stabilizing jacks are exactly that, as they will fail if used to lift the trailer.

When lifting the trailer with jacks, they should be place on the verticle axle mounting plate. For single axle trailers, place the jack rearward of the tires. For tandem axle trailers, place the jack between the tires. For the triaxle trailers, place the jack between the middle and rear tires.

Stabilizing jacks that are not mounted, should be placed on the A-frame and the frame at the bumper. For longer tailers, another stabilizing jack can be placed between the 2 axles on the axle mounting plate.

Stabilizing jacks should NEVER EVER be used to lift the trailer.

Andy

What is the reason Dexter says not to use the scissor jacks at the axle. I see no difference between driving a tire up on a leveling block and jacking it at the axle under the frame mount. It would seem to put the same pressure on same contact point

You would most likely crush the axle using a jack under it, I use a 12 ton hydraulic bottle jack on the frame mount with a piece of 1/2 " steel between the frame and jack so the pressure is on the verticle surface and not on the flange as it will bend.If I had a scissor jack , I would toss it, a 8-10 ton hydraulic jack can be had for $30....

I am in the process of installing FOUR 30" scissors in place of the TWO broken ones on the bumper.

I weighed the two originals with brackets. I am adding TWO extra pounds so Andy's comment about adding weight is true but not that much to be worried about.

For me to replace with ORIGINAL jacks it would have cost me $135 for TWO vs $65 for FOUR scissor jacks. Installation is a wee bit more for four but I now am going to be a lot more stable when I set her up.

Of course I am not installing them back where the original bumper stabilizers are and am installing them by welding directly on the frame. I failed to mention that I am about 90% done with a 65 Overlander restore and am in process of getting ready to install belly pan.
