I got my second battery tray from LMC many years ago and, as I recall, it was not cheap. It was not a good fit, but I was able to tweak it and make it work. You can get battery trays off ebay that are supposed to be epoxy coated.

If you decide on dual batteries you should get two new batteries at the same time, since the older battery will run down the new battery, unless you do have an isolator.

I now get my Interstate batteries from Costco - about $90 each for our old trucks.

Also, I recommend installing battery mats which you can also get on Ebay. You will need to remove the battery mats and clean them off periodically, but they do capture battery crud and slow the rotting away of your battery trays. They are like a dense felt material.
