I'm currently using a 15gal rolly tank, though I own some 7s so may explore going back to that. As to the utility if having a built in tank, I have been finding that for weekends, 20 gal is about all the gray I make, and am thinking that being able to just run a hose to a dump station at the same time as I dump the cassette would be handy. For longer stays or more people, the utility of having it in board is much lower, or non existent.Re: Installing a Grey tank on a PUP, asking adviceThanks, I will make sure to have the riser go all the way up.Installing a Grey tank on a PUP, asking adviceSo I have been planning on adding a grey tank as part of doing a full heat trace and insulation job on my palomino PUP for late fall and winter use. The fit and mounting fur the tank is fairly open, and as far as mods go should not be too challenging. However I'm a little worried that I have never seen anyone else with a refit gray system, so I'm here asking: What am I missing ? Is the low venting a big issue? Thanks for any insight. -- Bill
