Haha! Not easy, but it's looking good!
It's good to hear at least some of the parts have been improved! I have a couple of both the old and new versions still to build, so it's good to hear that it's now somewhat (haha, not really) easier to build. As I recall you should have fairly/relatively straight forward construction from here on.
The only part I clearly remember having troubles with is getting the rear wall of the cab to set correctly - sorry about that poor description! As I recall, it was tough to get the rear wall flush with the sides and the roof (?), and "around" the interior. You can see a couple process pics on my build here in the Dio section called "Rough Road, On The Road Again" - I built an A'stan version providing sentry.
Ok, Jay! Keep building
Cheers
Nick
