I have had 2.
I took my old system to the Rubicon.
The coleman tank system. Just like this. But clean up is a bit messy. Wife did not like so much.
PETT is probably the best known but spendy at 75-100.00 price tag.
I found this at Walmart for 25.00, very similar to the PETT. No splash back.
folds flat. IH8MUD sticker fits great on lid!
