on the last cruise my exhaust kept falling off, ended up driving home with it held on with 1 cable tie, and some plastic stuff ken had in his boot.
A piece of the exhaust its self is a piece of pipe with a plate welded on the end and 2 holes drilled in the end.
My fuel return line is blocked by a hose with a bolt screw into the end.
Ummm... Cd player is cable tied in with a piece of cardboard box under it to make it sit level.
Thats all i can think of for now
