Thanks for the reply Neil. I appreciate it.
I was looking at a 350kg indispension unit. For a small light dog trailer do you think that would be sufficient?
When you say a T frame, what do you mean by that? Is it steel going to the pull bar and then across the middle of the trailer to bolt the indispension unit too?
What would be the best steel to use?
Apologies for all the questions and thanks again.
