Interesting to see no replies about unnecessarily loading into your home septic tank. These are designed for the home and not for extra (necessarily).
A healthy system will "cook" on its own with almost no outside action (Rid-x, etc.) and if healthy, will require less pumping (1-10 years depending on you and what you put into it).
Start dumping larger amounts routinely (40 gallons at a flush/dump? Of course these are TCs so maybe much less than 40 gallons) and you are likely to unbalance the system, disrupting the micro-biology critters at work. Result? - more frequent "pumpings".....
....But if this thread just gave you ideas and now you're going to dump into it all the time when you get home, I advise caution....
Kind of hard to see '40 gallons' as excess... a ten minute shower is 40 gallons easy.
Solids, even if you dump a 'pile of...' all at once, will just go into the tank and push out an equal amount of effluent. Same thing a long shower would do.
I argue the septic system doesn't know the difference between having Thanksgiving guests over...and the effects of multiple showers for the day, excessive flushing, more dishes, etc, and a dump from your RV.
