How to jack a trailer for a flat tire change??

No way would I try to jack a trailer by the frame. Way too high in the air, especially along the shoulder of the road or on soft, uneven ground.

If you look at the axles, they have an arc in them from the factory, they aren't really straight. Lifting at the center can change the arc and throw things off.

Well, that was my point. I have always jacked trailers under the axle at the point where the spring pad/u bolts attach to said axle. I was attempting to explain the reason ,IMHO, why the - oh forget it.

Jacking the axle at the ubolt raises the axle by compressing the spring so the tire can be removed. One does not need to jack the trailer, especially when stopped precariously on a sloped shoulder of the road with vehicle wake turbulence hitting the trailer.

Stated I was about to purchase and was told there are 2 versions. One certainly will not life a high framed 5er and the 'pro' version is iffy.

I had a Pro Version and my MorRyde 4000 had 4 inches of movement and even with 2X6 under it the tire were still firmly planted on the ground. I ended up selling at a rally to guy with TT that work perfect on. I carried around for 6 months before I tried it just to see if would work.

I use 3 inch channel. I cut the top off letting the bottom set on the axel then I welded short pipe in the middle for the jack screw. This is solid and releases the pressure along the axel.

I used to carry the trailer aid. The first flat I had, I was in the bar ditch. The first time I tried to use it, the tire would not roll up on the T aid. It just pushed it.
I finally got the good tire up on some boards that I carry. I had to dig out the ground under the flat. Got the tire off. Had to dig more to get the spare on.
I still carry boards. I carry a reg bottle jack and a short bottle jack and a shovel.
A "regular" bottle jack will not get under an axle with a flat tire.
I got my short bottle jack from Northern Hydraulics. I think it is about 5"-6" tall.
Options! Always have options!
Good luck!
