The problem with enzyme/bacteria based produces (I like RV-Digest-It) is the time needed to work (72 hours). Treating your holding tanks like septic tanks does not work (IMO) since most folks dump as soon as they are full.
Someone did a "shake test" recently on TP but I forgot what brand it was.
Since I always dump; then turbo flush, we use the same TP we use at home (Charmin Ultra-Soft). Yes, the sheets come out mostly intact, and flushing at the site takes a good 15 minutes; but we are used to a degree of comfort in that area. If rushed at the dump station (or forced to use the "Blue Boy"), we do a really good turboflush when we get home or at the next campground with full hookups.
5 years down the road and we never have tank odors.
The Horst black tank probes we put in (year 2) work great and have never indicated wrong due to "TP hangup."
Once a year (at winterizing) we do a 1 week treatment of RV-Digest-It to all tanks to remove any dried junk on the roof or upper sides; then a long flush out.
