Had the blackwood lumber on my diamond C gooseneck before my current one, it was pretty cool. Lots more grip than steel and seemed to hold up a lot better than the straight wood decks.
Switched to a hydraulic dove for the my big trailer and ill never look back. Dovetails just drag on everything, the slope into my shop is marred to fuck from the bottom of the tails of trailers.
but to keep this somewhat on track, i agree with
BUCKLAND the 16' is the ticket as it can wear more hats than the single axle trailer
