To me, this is a great idea.... Why learn the hard way???
Why take more time and/or effort to learn what others have already found out through experience or research???
Unfortunately, and we all know this is the truth, common sense is not common, and we are not born with all of the necessary skills, knowledge, and abilities for all things we may choose to try out in life.
For what can be a somewhat complicated process, especially at the beginning or after a "time away" (off season) and where mistakes can prove to be costly, I like having written checklists. Over the years, they have saved me heartache and usually only take a minute to use.
Items for your list for learning, but not necessarily as rules but knowledge that could be helpful or even improve safety:
Tires:
They have an age expiry. Do not exceed it, especially for RV tires. Ensure that you have good tread and sidewalls and replace even before "expiry" if warranted. Protect them from sun exposure as much as you can. Check and adjust as needed tire pressures before moving the unit each day of your travels. On trailers and 5ths, torque lug nuts regularly.
Do not exceed the speed rating of the tire (which is often well below the posted speed limit)!!! Doing all of these will greatly reduce the possibility of suffering a high speed blowout and/or other wheel/tire issues. Tires that are in poor condition, or outdated, are not properly inflated, or when the speed rating is exceeded (especially if combined with any of the other tire issues) are the leading causes of blowouts and other issues.
Weight:
Weigh your unit as loaded at least once per year, including checking each weight such as total weight, component weight (truck, trailer, etc.), axle weight, and even individual wheel weight, to ensure no overloading. Overloading any part can be dangerous. Many units (read more than half) on our roads are overloaded putting not only themselves but others at risk.
Hitches:
Ensure you have the right size and type for your unit. Load distributing with sway protection is usually not "overkill".
Sewer:
Never leave the valves to your tanks "open". For one, that will provide a direct path for sewer gases to potentially enter your unit.
Also, it the black (poop) tank is left open, the liquid will continually drain leaving a lot of the solids behind. This can dry out in the tank turning to a hard coating that is next to impossible to remove. Empty the black tank when 3/4 full, followed by flushing the lines by then emptying the grey tank. Invest in a "tank cleaning" attachment for regular tank flushing.
Your nose will thank you.
Route:
Especially when towing, always look ahead to ensure you will be able to safely travel that route. Don't just "trust your GPS". I know that they sometimes mislead and try to have you take roads that are not suitable for your unit!!
That's all I have for now. Other posters have covered many other items well. Personally, having once been a "newbie", having a relatively complete understanding of what is involved, instead of just "blindly jumping in with both feet", is always a better, safer, and more relaxing and fun way to go!
And many newbies can be overwhelmed trying to "find out" or worse yet just carry on being completely "clueless" of the dangers and risks they are (often needlessly) facing.
JMHO.
