Jim Betts here... I have a 30DS as well and really like the mods you've made.
I've done a number myself, but want to do a few more. I want to install a 5.1 two zone surround a sound and upgrade the TV. Also interested in installing the wash/dryer combo like you. You say the TV mounts right in the same bracket but I'm not sure how you did that, seems to me that the lift handle is only 18" from the top. Wonder how you did it and thought a 40" might fit a bit better.
Also curious about the wash/dryer combo - plumbing and power. More information would be great. If you have time you could give me a call at 416-254-2123 love to talk with you.
