2007 GMC 2500HD motor mounts

Ok, so I'm pretty sure my truck is to the point where it needs some motor mounts and a tranny mount. Transmission mount should be a piece of cake, but the motor mounts might pose a little challenge. I did some on our shop truck (2001 2500hd) a few months ago and they weren't too bad but it's also 2wd. My truck is a 2007 Sierra 2500hd 4wd 6.0L. The labor guide says 4-5 hours. I have all the tools I should need to do this but I'm getting fucking lazy and have considered paying a shop to do them. Has anyone tried to do these before?

I have not. What is it doing?

It moves quite a bit when you rev it in drive with the brake held down. I didn't really notice any of the usual symptoms of bad mounts. It's never been the smoothest shifting truck but now that I know the mounts are bad I'm noticing it more. I've got a little over 150k on it now so it's probably past due.
