Homemade Lowboy Trailer, With Bonus Seized Engine Revival!

I needed a trailer for my John Deere mini excavator, but I didn't have one that would work. Obviously, I needed to build one. Rather than buy a trailer axle, I bought an old Dodge D300, got the 318 (360?) engine freed up, and then pulled the whole truck apart. A little bit of quality time with a saw and a welder, and I had a DIY lowboy trailer.
