Jamie,
I was talking about the same thing when i collected dereks yesterday! I've seen a couple of videos on youtube from an american company a.s.a.p cleaning i think! they have both and they used both on end of tenecies with similer results! but i think the rv360i looks like its more for the domestic market and the rx is for the commercial!!!!!!! i like the fact of a clear pipe on the 360 so you can see what your pulling out!!!
