The HU looks good. You've got to put some amps in the plans down the road and take advantage of that bad boy.
I know how it is to get behind. I've learned a lot of patience waiting to build my burb. I'm about 1 1/2 yrs behind and falling. Since I finally got my suspension in, I've had one mechanical or electrical problem after another sucking up funds and time. It's a slow frustrating process, but in the end it's rewarding. I hope.
