Black water tank removal

[chinacreek]

I have a 1988 coach. All the Sanitron sensors that I can see are corroded and loose, some are beginning to leak, all six need to be repaired. I looks like the only way to do this is to remove the tank completely. Is there anyone out there that knows the procedure for removing the tank. It appears that which ever side I take the tank out on some plumbing will need to be cut and removed. Which side is the best to take it out from? I would like to avoid disrupting the fresh water side of the compartment but am not sure that will be possible.

Any suggestions would be appreciated.

Thanks; Charlie
