Then change tire and reverse the operation. Definitely NOT recommended for long term storage.
Using the rear stabilizing jacks or tongue jack to actually jack up the trailer so that the wheels are off the ground is not at all recommend by Scamp. Apparently a good way to bend the trailers frame.

As Carol says, don't jack the wheels off the ground using the stabilizers. They just what they say and only what they say "STABILIZERS". I put just enough pressure to reduce the amount of bounce when walking around inside the trailer.

Ladder frames are not all that stiff in torsion (twist?). The Casita manual also says don't jack up the frame using these stabilizers but I don't know if that's because of the flimsiness of the stabilizer or the flimsiness of the frame or both. They do say to jack on the frame when changing tires, but that is near the middle of the frame and a c-channel frame is relatively stiffer in that sort of deflection. Emphasis on "relatively".

Carol, Interesting you say that about Scamp and jacking up the trailer. It reminded me to share something. Last month I had a talk with a very nice guy from Scamp while they were showing their trailers at the MN State Fair. During our conversation he told me the best way to save wear on the torsion axle is to store the trailer with the rear jacks down and to crank up the front. He said it would add 10 years to the axle life. Now, he didn't say to raise it so the wheels left the ground, just so it took pressure off of the axle. He was the head guy in their welding shop and has worked their for many years. I wish I could remember his name. Frankly, Besides possible frame issues, I wouldn't feel safe working on the trailer or changing a tire with only the rear and front jacks. They'd be too wobbly with the tires off of the ground. Plus I wouldn't trust that the rear jacks would hold.

Ken

Taking a load off, so to speak, makes intuitive sense. If I were to go that route for winter storage I'd jack it up at the axle and slip jack stands under the frame.

4 if them, one at each corner.

Yeah. Jack stands would also ensure that nothing would move. Especially when considering Norm's feedback about his rear jacks slipping over time,

I don't know about slipping over time. I used mine for over a 1000 nights and have never known them to slip. The mechanism is designed such that the higher the loading the stronger the hold. I suppose that with a minimum loading and a lot of bouncing around inside they could slip, but not likely.

I've never analyzed the slippage but it's small, maybe caused by the trailer settling. Usually just takes a slight jack up.

We like the rear stabilizers. We have also added a 4th jack at the front door corner. This one is a more familiar screw down jack.

Norm, could the slippage be due to your using small wooden blocks under the stabilizers? I used wooden blocks but found in wet conditions the jack slid on the blocks or the blocks themselves slid on their own especially if stacked. Now use the plastic interlocking blocks under the jacks to avoid that & it seems to work.

Ken, yes Scamp does in their manual recommend taking the load off the axle if the trailer is not in use for long periods. Suggesting it helps the longevity of the axle. But the same manual also states one should not jack the trailer right off the ground using the rear stablizer and front jack.

Carol, that may be possible. It's never been much of an issue but I"ll pay attention next time. We leave in a few weeks.

The real advantage of the blocks is I don't have to extend the jacks so much. When I need length I get 4 more inches.
