Longarm issues

I like the figure a lot. Just some concerns...
I am just looking for more information on his transformation. I have trouble with his truck mode. The headlights won't prone into the position shown in the instructions. Doors won't shut down. The feet are hard to get back in place. His cannon used to shoot a lot harder and farther before, don't know why the effect went down. When standing, the top part sort of slouches downwards right, does that mean it's going to break? Like when posing him he doesn't stand straight up facing you. The plus is that it looks like he's strafing. Read on teletraan 1 wiki that there was problem with the hook, but I don't see it...

Maybe I played around with it too much...Longarm features a minor mis-assembly problem, in that the strut between the crane section and the hook itself is reversed. It is easily fixed by popping off the hook and turning it around, then unscrewing the crane part and flipping the strut. This allows the gun to fit together much better, as depicted on the packaging
