That's looking good! One suggestion though. Your trailer's fenders look like they need to wrap around the wheels a little more, so they match the tractor's fenders. I like the spread axle better. Either way, it's going to look good, but it's a little easier to model the norms, rather then the abnormal. Just don't see many tri-axle trailers around the US like that. That's not to say it wouldn't fun to model, because it's unique and cool, but spread axles are just more common, and they look sweet too.
