I'll just chuck this in the mix...cuz I had one....so good or bad...its first hand information.
If you want a work horse....consider an argo.
I'll add what I think the plus's were.
In the spring...u can cross flood waters, muddy spots with ease. No getting wet. Other times of year....water is still not an issue. I had a little electric trolling motor mounted on mine and it was awesome for lakes etc.
If it's roofed.....what a great way to keep black flies off when driving slow....or if working in the woods...a great retreat from them to have a bite or coffee etc. Not too mention weather etc. And....it goes up and down pretty easy....so u can put it up, or down, as need be for the day,
As a go anywhere beast...pretty hard to stick one with 6 or 8 wheels.
It's a boat ( with motor) and atv rolled into one.
With the tracks on ....it's a year round machine.....
They can carry a gawd awefull load without complaining or too much fear of tipping.
Without a load 4-6 people with ease in the 8 wheel.
As mentioned....size can be an issue and these are big machines for transporting and going thru timber. They are a bit of a maintenance beast...but mostly just greasing it regular. If I was to get another....I think I'd opt for the 6 wheel...just for size.
