I like the list and the additions later on. The lego blocks are good i have used mine well so much so I have ruined two...have a new stack now.
Now when it comes to toilet stuff, good old Costco TP works well, and i have not used a chem for at least 5 or 6 years...just have not had the need. Extra cost and got to carry it someplace and hope it doesn't spill, ever tried to clean up the blue stain after it dries? Why gloves, just wash your hands! it is your stuff, why worry!
I carry electrical adapters for 15 to 30 to 50, extension 30A cord with an LED light so I know I have power.
All sorts of water stuff so i can get water from almost any tap.
Quick connectors for city and flush different heads so they are not mixed.
in line shut off always handy/
Short flex with pressure reducer in line makes it real easy to fit on almost any tap.
What are these called, slip it over a tap with out threads.
\
four way key, any good plumbing supply has them.
tank fill long enuf so it stays in place with shut off.
All my hoses have new cast brass fittings, not stamped, so they will take abuse plus they just work better and do not cross thread.
Plus a fitting that goes inside a tap that had inside threads...they are anti tamper hose bibs and the thread on the outside cannot get destroyed.
Hose to hose coupler...3/4"
Carry a Weber BBQ and the hose to feed from the low pressure LP.
It was easy to remove Weber reg and replace with good airhose fittings.
