I just purchased my new 2017 Ram 2500 mega cab short bed. I have a trip fold cover. Looking for wheel well boxes that meet certain specs. Any thoughts on who might have these?

1. No top open / load. Only a door on the back. Do not want to open cover to get into storage, just drop the tail gate and access.
2. No swing out. Useless if the bed is loaded.
3. Drawers in one, open cabinet for the other to hold a fire extinguisher, jumper cable set, mini compressor, etc.

Thanks!
