Our old cheap toilet you can't get parts for anymore (dual flush). I remember my dad fixing old singl-flush toilets with just standard parts from the hardware store. But these new dual-flush toilets are super proprietary. Are single-flush toilets more standardized to where I would be able to easily find parts? I am thinking yes, but the plumbing parts store says otherwise. Am I missing something?

Edit: to clarify, my wife and I hate the dual flush so we're going to buy a new toilet. I'm more wondering if the NEW toilet will be easily repairable. Sounds like maybe the old one is more repairable than I thought, though.

My wife and I like to car camp in the back of our Toyota Highlander on occasion, but I love a long hot shower and not everywhere we camp has a shower house.

Anybody have some cheap solar shower ideas that have worked for them? I know about the hanging bag ones but seems like those would make for a very short shower. We also may not always have a tree or good place to hang a bag shower.

I thought about just a big HDX tote up on the roof rack with a spout attached. Or maybe we just need an RV 😂
