2005 vs. 2006 H2

[Woogy]

So, I'm looking for an opinion and I was hoping there might be someone on this board who can help.

I am trading in a 2003 H2 for a new truck. The dealer has a 2005 with exactly what I want and is offering a pretty nice deal. Generally I would go for the 2006 and wait a little while.

Do any of you know the specific changes (if any) GM made between the 2005 and 2006 model year?

In addition, any thoughts on picking up a 2005 this late even with a good deal?

Thanks in advance for the insights.
