Well I am almost back on the road. I jacked the trailer up, dropped the chassis, and had every weld redone and added some extra strengthening.
More detail in this tread.
Getting the chassis aligned and bolted back on was the difficult part.
The trailer cabin, was surprisingly undamaged, with some trim lifted at the corner. The only real cost apart from the rewelding was buying two new light clusters.
My better half took it pretty well. So hopefully she will feel happy for us to tow the trailer again.
All I need to do is wire up those lights and we are all set.
