I get pretty tired humping 30 to 80 pound rounds 50 yards out of the forest and back to my truck, one by one. What do you think of this hand truck for this purpose. It has pneumatic tires. I cut my rounds to 16" thick, and very, very rarely exceed 18" in diameter. This hand truck looks like it could hold 3 rounds and still be way under it's 330 pound capacity. That would mean 1/3 the trips, and a lot less effort. But if you see something negative about it, let me know.

I have several hand trucks and a lot of experience using them, including a super heavy duty model designed to move 55 gallon drums of whatever, heavy stuff. On hard ground, they work great, any slopes or irregularities or soft ground, they just suck. Wheelbarrow is king for moving stuff around uneven terrain. As long as not overloaded, say..you can carry X size round, go 3x in the wheelbarrow and it will still be mostly easy and controllable.
I also have one of the folding sides wagons illustrated above ^ and it works OK offroad, as long as you watch it on slopes, it can tip sideways easy with a load on. I've dumped mine a couple times..rather a PITA... much heavier than a wheelbarrow as well and clunkier to get back up onto your truck, on top of your wood score, at the end of the day.
Wheelbarrows are an ancient tried and true design that just works for manpower moving clunky stuff from point A to B over most any terrain. That would be my first choice based on use and cost.
In the winter, if you have good frozen ground and snow or whatever, a toboggan.
The Dr powerwagon looks spiffy. But, then you need a trailer.
If you can tote a small trailer, with your truck, a cheap used riding mower, take the mower off, chains and liquid filled tires, small garden cart trailer, you're in biznezz if you want a fuel burning thing for cheap, just as an alternative to that powerwagon. That would be light enough so you could detach after unloading the mower and trailer thing, turn it around by hand, then hook your truck back up heading back out. Anything too heavy would be a pain to turn around in down old fireroads.
I just like a wheelbarrow myself for past where I want to carry or roll a big round. And they are light enough to chunk back up on top of your load and strap it down for the trip home. Just don't fill it all up like you are moving around your yard a short distance. For me, your mileage will vary, about 3 times what I can hand carry and I can still go uphill, maneuver around roots and chunks, etc, pretty well, and speeds up the process and doesn't wear me out. I can put more weight in, it will fit, but then gets to be sorta stupid once I want to move it.
With that said, I have wondered about something like a two wheeled off road tires rickshaw looking thing. Get a good balance over the axle with your weight, and you get to pull rather than push with a wheelbarrow. I am not aware of anything like that for sale though, but I bet it exists. You see pics of two wheeled carts with humans pulling them in like third world countries, with some impressive loads on them.
Maybe take a single axle garden cart, lose the single pull beam, adapt two long handles to it instead, something like that.
Or a wheelbarrow, bolt some extension handles to it and pull it instead of pushing it. Pulling works better than pushing in a lot of cases. I'd unbolt the cargo part and turn it around and rebolt it, if I was to do that. That and lower the rear skid parts to get better ground clearance. Be some cutting and welding or bolting involved then.
