This may be of interest to you guys. I use a free app called "AnyList". I use it for cooking, but I ended up using it for ALL my lists. I have an RV list. One category I setup, is Maintenance. Notice the ability to embed a picture of screen snap shots or a picture taken on the phone. This gives me instant info, I pulled from the manual. You can also put hyperlinks in you notes as well. Attached are a few screen shots....I am a geeked out caveman..LOL
Pic #1--This is what it looks like on your phone. Notice I have Mobile Tech's near me (Thought I might have needed extra pair of hands)
Pic #2--What it looks like when you hit the embedded manual pic I circled
