Episode 198 – The #1 RV Toilet Upgrade Mistake (And How to Avoid It)

In this episode, Eric Stark breaks down the #1 mistake people make when upgrading an RV toilet: assuming the new toilet will connect the same way as the old one. The floor mounting is usually straightforward, but the water supply connection is where most upgrades get hung up—different fittings, different angles, and sometimes a water line that needs to be replaced or adapted. Eric also covers what really matters when choosing a replacement toilet (spoiler: it’s not the brand name). You’ll learn the measurements to check before you buy, including the bolt spacing and the “back-to-wall” clearance that can make certain upgraded models sit too deep or not fit at all. Plus, listeners are invited to share what black tank treatments have worked best for them, and Eric wraps up with a look at new Camco sewer hose fitting upgrades designed to make hookups easier and more reliable.
