Do you have a DSL filter on the line going to that DSL cable?

no help.
I know distance is not an issue because I tested that too. I "looped"
back the DSL line back down to where it comes in main telephone room
( basically doubling the distance) and it works fine. So I'm thinking
this is more of an inteference issue. Any ideas where to start? The
trailer is next to an MRI facility, not sure if that matters.
