Raising trailer on jack stands

It seems like a good idea to store a trailer (25' Safari) for the winter raised on jack stands or scissor jacks to keep the tires from getting flat spots. The manual describes the two jack lift spots behind the rear axle, but no other info. Since the two rear jack locations are the only ones, I would assume I could raise the rear carefully, one side at a time, and in addition, use the tongue leveling jack to lift and level the frame. Then drop the stabilizing jacks to firm it up. Any advice from the factory or experienced advice?
Thanks Dave Ingram/Colo

Dave Stabilizer jacks are just that. They are used to stabilize the trailer and are not designed or intended to support the weight of the trailer. I have seen people here who have raised their trailers up off the wheels and they ended up bending the frame by hanging the axles in the air. The weight of the axles and wheels caused the frame to sag. They also had problems getting the entry door to close and the slide out rooms to move. I would leave the tires on the ground and only put the jacks down to support the trailer. What`s cheaper new tires or extensive frame and shell repairs.

Hi Dave, welcome to the forums. You will no doubt get a lot of opinions on your questions, some will be pretty good. I'll throw in mine. Lot of bad things can happen to an Airstream jacked up with the leveling jacks down. Tires are cheep when put in perspective. I leave my tires on all the time. May take one off at the time, but at least one is on to catch a fall.
Good to have you aboard. I'm no expert nor have any factory sense.
Warm regards,

Joe

To support wasagachris, supporting the frame is okay, lifting the frame at those support points is not okay for storage.

It seems more viable that you take the trailer out for a spin every couple of months off season, to move the tires and exercise the torsion axles, than that you jack it up and artificially load up your frame.

If you want to unload your axles and tires why not jack up the trailer at the two jack points and place blocks to jack stands under the frame between the axles and then lower the trailer onto those. Leave the tires in contact with the ground and it makes it more difficult for someone to steal your wheels.
I would not put the levelling jacks down to prevent the possiblity that the blocks sink into the ground and leave the trailer supported by the jacks.
Mine always sits on the tires ready to go, even though I don't use it for about five months through the winter.

I assume, by your post, that you are talking about the jack stands manufactured for that purpose and properly rated for the trailer weight, placed under the axle plate which the axles are bolted to. These would bear the lion's share of the weight and the stabilizer jacks lowered to offer stability only just like when you're camping.

I think this is fine and is best for the tires as well as the axles.

I am on concrete so I do put down the stabilizers for the possibility of instability in gusting winds. I also leave the tires on, barely contacting the ground with covers on them.

I think you have described a very good thing for your tires and axles. Since you indicated that the weight of the trailer would be on jack stands and the stabilizing jacks would be only for stabilizing and not weight supporting I do not see where any damage would occur. (As long as the trailer does not fall off of the jack stands or the jack stands do not sink into the ground) The method you described is exactly what I do except I do not have any stabilizer jacks. I place my jack stands under the axle mounting plates, leave the tires in light contact with the ground, and cover the tires for UV protection. You are located in Colorado, so taking the trailer out for a ride every so often might be thwarted by deep snow and drifts like I have at times in the winter.
I think you have it figured out well.
Sam

Is it a bug? Is it a plane? No, it's... oh, wait... It's a bug!

Dave,

All you have to do is move the trailer forward or back every couple of months. I put old plywood pieces under the tires to keep them off the ground—it's supposed to be better for them.

I do it mostly for the axles. This stint of downtime is 5 months. It sucks but that's the way it is for us at this stage of life. Wife is a school teacher....no vacations per se for 9 months a year. I kept my old SOB on the tires always. Never had a tire issue with it with respect to flat spotting.

Gene, yes, that is all the tires need, but it must surely be good for the axles to take them out for a little exercise now and then?
