R25OB black water tank location

[trailertrawlerkismet]

For the R25OB I’m wanting to find out how accessible the black water tank is, as well as where it is accessed from? Lastly are the overboard discharge pump, hoses n fittings in a position to be worked on if needed? I’m asking because of converting the black water tank (new n never used) to fresh water and connecting it to the house water tank by an diverter on our soon to be built RT25OB. I’m looking at installing a composting toilet to reduce pump out time, reduce odors and increase house water supply.

Jim, it’s been a few years since you’ve done your modification to connect your unused black water tank to your fresh water tank on your R25. I’m planning on getting a waterless dry flush toilet (Modiwell R1808 RV toilet) to do the same when my new boat (2026 R25) comes in. What an ingenious way to increase your water capacity on your R25. As it’s been a few years, can you advise how that merge is holding up? Any concerns or things you might have done differently the first time around? Would love to get any input here. Thank you!
