It depends on what I'm doing. If I'm in an area that lends itself to bunching logs by the trail, I'll often use the winch to pull them trailside and cut them right there. Any time I need to mover longer lengths, the forwarding trailer generally gets put to use: Bringing out logs for one of our community firewood volunteer days, saw logs (I don't have a mill, but occasionally barter with a friend or two that does), or when I need to pick up move firewood logs off-site.
Since you asked, here's a picture of a load I picked up that was about 25-50 feet off the side of the road, where someone was clearing the powerline right-of-way for their new house. It was a hard maple that they were donating to our firewood donation "WoodBank". (They cut the logs a bit shorter than I would have liked, but I'm not going to pass up a donation of such a prime firewood species.) I used the hydraulic winch on the trailer to pull the logs to the side of the road, then loaded the logs on the trailer. This was a case where I was glad the previous owner had ordered the trailer with options. The winch is much slower than my 3 point hitch logging winch, but it's very handy: the grapple only has a 9.5' reach, so the winch saves a lot of repositioning of the trailer. The little Honda engine powering the hydraulics allows my to run it behind a pickup truck, rather than making it dependent on tractor hydraulics.
