Hello Bryon,

I'm a light weight person, and I don't like them either!

If you're looking for an RV toilet that feels the most like the one you have at home, the Dometic 420 RV Toilet - Standard Height - Elongated Bowl - White Porcelain # DMC67JF (Tan # DMC77JF) is one of the best choices available. The elongated bowl and standard height make it much more comfortable than the smaller round bowl RV toilets, especially for taller or heavier users. It has a residential feel that a lot of RV owners appreciate after making the switch.

As far as the biggest RV toilet made, I can't honestly say that the # DMC67JF is the absolute largest on the market because manufacturers don't publish a standard ranking for bowl size. What I can say is that it is one of the largest and most residential-style RV toilets we carry, and it is about as close to a household toilet as you're going to find in an RV. If comfort is your top priority, I would not hesitate to recommend it.

I've attached an image that shows how to measure your rough-in. The # DMC67JF requires a 7.625" rough-in measurement, which is on the shorter side, so there's a good chance it will fit your RV. That said, I do recommend double-checking before ordering. Simply measure from the center of the toilet flange, or mounting hole, straight back to the finished wall behind the toilet. As long as that measurement is at least 7.625", you'll be good to go.

Sorry for the delay in getting an answer, it took a while to get this toilet live on our site.
