I'm going for the simple swap but that said I remember a while back the base of the toilet had some operational stuff in there so it couldn't be done but that was 25-30 years ago on a FAN trailer.

On short toilet sometimes folks will add a spacer on the bottom to raise the unit. It's held in place with bolts. Good luck!

Welcome mbass777 to irv2.
What you have maybe a offset because the black tank may not be directly below toilet. The drain pipe is at an angle in raised box.
If you can see a straight short into tank you maybe OK and the box was installed to gain height for toilet seating.

I wish I knew more about how black tanks and RV toilets are set up before I did my bathrom mod. One of my main objectives was to re-set the toilet just a little bit farter away from the side wall (shoulder and backside room).

1) Some tanks use a rubber grommet thing that the ABS pipes *slip* into. Some don't. These others use a fixed fitting that the ABS is glued into.

The grommet fitting type are a whole lot easier to allow modifications and changes. Learn which type you have asap as EVERYTHING subsequent stems from that.

2) Mounting bolts and flanges. 99% of toilets in the US and current RV types use the standard "9&3" bolt pattern. Older RV toilets use a "5&11" bolt pattern.

3) Thetford makes a nice toilet (Bravura, about $200) that can go onto the older style 5/11 bolts... AND will set higher than the older unit.
