Trailer new to me, what is the pictured dip in the frame for?

Drywall suppliers around here had trailers similar that they towed behind a flat deck ( loaded with drywall). the trailer would be loaded with a very large telahandler with the front wheels set in the wells to reduce the height. It’s more common now to see a lift on the truck instead of a telahandler. Cam

I'd have to see it to understand I guess. If I take a hard left, the truck tandems are left of the trailer center line. Hard right would create same issue, different direction.

I guess if you were very careful and minimized turning degree you could get by with the sliding you are talking about.

I hauled it that way for 24 years. I owned three backhoes. A dozer, crawler loader, 2.5 yard wheel loader and some compactors.

Cool. Glad it worked for you.
