Pictures of the site would help.
Here are some photos but from your last post it does not sound like this is an option. Possibly if lightly loaded?
Not a fan of dragging stuff myself.
If you can fabricate then space saver spares, and spindles off the back of front wheel drive cars are an option.
Four bolts and they are yours for pretty cheap at most junk yards. The junkyard near me uses two of them per wheel barrow for customers to get their toolboxes and parts in and out of the junkyard. But you could make most anything out of them.
This is what I have used, and found...
Note however, the terrain here is surprisingly flat. A log arch or loaded trailer can have a lot of push behind it. I'm certain I have pulled maybe 1,500 lbs., possibly more.
A log arch is nice, but are a limited use, specialized piece of equipment. You still need the trailer to clean up the smaller limb wood.
A trailer is far more versatile for all sizes of firewood, and and of course many other things.
Our trailer is loaded with splits weekly, and parked in the garage most of the winter. Summers we use it for moving firewood, bark/mulch, yard work, and sometimes as a temporary or mobile work bench.
There are walk beam axles and torsion axles. This trailer has torsion axles. Nice when unhooked, as it sits pretty level, and it can be moved about. Not so good traversing steep berms or road side banks, as all the weight can at moments be carried by one axle, the other air born, either front or back depending. It also has an electric dump. This brand is no longer available but there are others very much like it that are. Very handy tool connected to a quad. After ten years, the initial cost is mute. (Actually the cost has almost doubled in ten years time)
