In the army we had a terex telehandler, I don’t know the model or anything, but it was big, it had outriggers, I’m pretty sure it had 4 wheel drive and it had leveling hydraulics on the axels so if you drove slow enough it was like being on a perfectly smooth road no matter what the terrain. It could steer with all 4 wheels so if could get in and out of some tiny places….
But I didn’t drive it all that often so I can’t guarantee any of this information. I liked the bobcats better for what we did anyways. They moved faster and I could do wheelies when I was bored….
On a side note there were also terex’s they used to move shipping container. It must have been 20 feet wide, 30 feet long, and 40 feet tall. it took up the entire road when it moved around with trucks in front and behind it to clear the way. Everyone would just stop and stare when they passed, like watching a small building move…. Well in Iraq, it was like watching the largest structure for miles move. And it was covered in warning lights, for dramatics… we all wanted to find out what driving it was like, but they maxed out at about 10mph….
