Yeah I guess I was excited and it all flew out of my head. Yes it's a 6' bed.
See I was thinking it was much larger and would just barely fit on an 8' bed. That lathe is actually worth more being smaller. That's what most hobbyists want. Smaller will be a big plus if you ever go to resell it. It's still a BIG lathe as hobbyist lathes go. Like I say, I'm jealous as all get out.
Those chuck look to be in excellent condition. If that was in a school it's amazing that there aren't any signs of crashing into the chuck. That's the first thing I looked for in those photos. And I saw the photos on eBay so I was able to zoom in pretty close. Those chucks look pristine to me. And the collet closer is another big plus, even without the collets, you can acquire them as you need them.
As far as not following my advice in loading the lathe, you're not alone. I almost never do what other people tell me to do.
The good thing is that in your case it all worked out well.
The reason I mentioned about putting it on the truck headstock first is to get the major weight in the center of the truck. Having the bulk of the weight at the tailgate end can result in some surprises if you need to make a quick swerve on the highway to avoid an obstacle. The next thing you know the headstock is tossing the truck around in ways you may not have been prepared for. Of course that's not going to be as pronounced with the smaller lathe in a 6' bed. But put a much larger lathe on an 8' bed with all the weight at the tail end of the truck and you'll quickly notice that it affects how the truck corners. I learned the hard way.
Fortunately no major accident, but a scary ordeal when the lathe starts driving the truck for you. You slow down real quick! I'll never do that again. Put the weight to the middle of the truck. Good rule of thumb.
