Have you looked at the DR Versatrailer pro? I've used it extensively this year for log and split firewood transport. Very well built and pulls easily behind Kubota
BX2200. It's similar to the T-Rex.
Yes, I've considered the DR Versa-trailer. (I live just a few miles from the DR headquarters in Vergennes, VT - unfortunately, they don;t have one there for me to see last I checked.) It's not just similar to the T-Rex, it's identical, from what I can tell. It's either made at the same Chinese factory, or DR cloned the T-Rex (DR does have a habit of cloning successful products made by others). Glad to hear that it's holding up and working out well for you. That gives me a bit better feeling about considering them.
I'm leaning toward the Woodland trailer type, rather than the T-Rex. Reasons for this: I won't use the boom crane on the T-Rex (or Versa-trailer) to load logs. I'll use my tractor, to load from the side, or use the winch to pull logs in over the end. Since I don't really need the boom, the fact that the boom crane on the T-Rex / Versa-Trailer limits dumping to 650 lbs and a 35˚ angle, while the Woodland Trailer can dump the full 2000 lbs and reach an angle of 60˚ makes the Woodland Trailer a better choice for me (we have a lot of sticky, clay soils around here, so the steeper dump angle is a real bonus). I'd consider DR's trailer if they made the Woodland version, and if they got the price down: Their regular price for the 1 ton model is $2400. Even on sale at $2000, that's still $300 more than the Woodland Trailer (maybe more, if it turns out the Woodland Trailer prices are in Canadian $).
I'd really like to find something similar, but that will handle 3000# (half a cord of green Beech firewood), but I may end up going with this. I expect going bigger gets a lot more expensive, and maneuverability in my woods is a concern.
