While I was working on the door, I was debating constantly with my wife on replacing the bed, or building a custom bed.
Completely replacing it with new parts and a metal floor would run $3000 (pretty much every part needed to be replaced).
Here is the bed, and removing it by myself wasn't really that bad.
So, based upon my estimation, a custom built bed would only run $1500. Knowing the amount of welding I'd have to do, I went ahead and bought myself a Hobart Mig 140 as a christmas gift to me.
