This review is a little unfair. I thought my toilet drained straight down to the black tank. It turns out there is a slight displacement in the neck of the toilet drain - a bit more than this wand can accommodate. That is not a dig on this wand. Rather, it is my fault for buying the wrong tool for the job. I need the flexible wand. I will buy that next. From what I can tell, this wand puts out a potent stream that should do a great job blowing the crap out of your RV crapper's black tank. So, if your RV toilet drains straight down, with no displacement, this wand should work great for you.
