Had the Natures Head Composting Toilet option selected on my 2022 Elite (canceled) build, after I found & purchased a 2020 Elite #643 with the standard toilet. Have found the black tank fills first & need to break camp to dump. Researched converting the Elite to composting, but hate the thought of removing a perfectly good toilet system. The thought of cutting & drilling fiberglass, plumbing, plus adding wiring, not to mention the $1,000 + cost.
My personal solution: Modify my standard toilet with a urine diverting bottle system & extend the black tank capacity. Mission accomplished @ a low cost.
