question about using toilet when hooked up at home

We installed an easy access to the septic tank at home for easy pumping. (No more digging to find the concrete hatch or the tank). There is no actual "clean-out" on lines, the lines run under the house, under a concrete slab. (at least half the house does). But the easy remove lid works great now when we need to get it pumped out.

But the pipe is a bit high, so I built a very simple ramp using just cinder block and 2x4's and 2x6's. They aren't nailed or anything, they are just sitting there, easy to remove if I need to or any reason.

Meanwhile, it now makes a great ramp for my blue tote. I've been doing it this way for 3 years now with any problems. This works great or me. I don't mind using my blue tote. The distance the trailer is parked is too far and would require tearing up my asphalt drive way in several places to run a separate line just or the trailer. So, this works very well for us.
