Good Stuff

Good stuff, I use the less expensive stuff routinely and use this Thetford Blaster twice yrly, when head south for winter and north for summer. We travel a couple hundred miles on our first day, short day, so we put the packets in with just over a 1/3 tank of water. Works pretty good sloshing around for a few hours while traveling.
