The 30 year old, 100 pound chunk of lead they called an ice maker was the first thing I eliminated on my Barth in favor of a dometic countertop unit. The hole that was left perplexed me, it had a good size and an outlet. Then it hit me, indoor shop vac storage, and with an additionl hose it's like having a built in vacuum! Had to share, it works too good.

That's a good idea. I was pondering the same question...what to put in that space. My flux capacitor won't quite fit.
