Sorry I haven't been here in a while. I found out a few more very interesting things about this fantastic AT-AT that nobody else on the net mentioned. The pictures are not the greatest quality, because I ran out of batteries for my camera, so I had to use my mobile phone. Here are pictures to Illustrate what I mean:
You can actually fly Luke's Snowspeeder between the AT-AT's legs just like in TESB, but they need to be just a few millemetres apart.
It's possbile to get 22 Imperials in the main hold believe it or not.
Here is the AT-AT's head with the vintage guns from 1981. Unfortunately one side will stay on, but you may habe to put blu tack on the other gun to help it stay on.
I have two Imperial Speederbikes in the back garage of my AT-AT at the moment side by side, with five Imperial troops standing single file down the centre.
Here's one of the Speederbikes through the side window.
The 2006 General Veers will fit in the back of the head with a Snowtrooper standing beside him, but unfortunately he will not quite fit standing directly behind the two AT-AT drivers.
