Good luck!

When you recamber it I'm curious to find out if the shop finds a bend on the axle tubes immediately outboard of the frame attachment points. You axle arch flattening in itself doesn't sound like its really bad enough to cause the negative camber in your photos.

That is exactly what I want to know. I am no engineer, but it has to be relatively easy to flatten out that tiny arch than to bend the last foot of the axle tube at the frame attachment point. BTW, the welding skills shown in this thread are top notch!

Back from the alignment shop and here is what they found. Beside the negative camber it was also 1/2" toe-in, this is why I align all my trailers, I gained 2 mpg after aligning my off-road trailer. The axle was not bent outboard of the frame and that would be really hard to do with a Torsion axle, they are almost solid the first 20" or so and hollow in the center.
Before.

After.

No before picture, but my axle was flat.

On the rack.

Wow, that's a lot of camber you wound up with!  For camparison to StephenH's new axle, and to my axle, do you know how much gap you have there now? 

Thanks

More importantly, how did it tow with the new setup? Also, is the place you took it to for the alignment a national chain? I have not heard about trailer alignments being done before this.

I am going to Measure it today. Axles should be aligned to the trailer after installation and I don't think Forest River does it to each trailer. They did not even build the frame right, it should have been 10" wider. And if you have replaced your axle it should be done just like when you replace parts on your car or trucks suspension. I align all the trailers I build, and all of them needed something. If your trailer wheels are not straight up or real close to it or are wearing tires odd, you should have it checked at a good frame shop.
My trailer pulled good before, but the tires were cupping. The shop here is just a local one, I would look for a frame shop in your town that the trailer repair guys use.
I still need to balance tires.

Have you had the opportunity to tow with the reinforced axle? If so, how is it working out?

+1 to StephenH's question.  I simultaneously asked it in the other axle thread that's in current discussion.

Any updates about performance with these installed? Are they staying where they should or are they slipping? It would be great to be able to get something like this to be able to bolt on. What if the attachment to the frame were an L-shaped piece that would bolt between the riser and the frame instead of being welded to the riser? Would that work and be able to be fabricated easier than welding the top support to the riser itself?
