Does anyone put a makeshift P trap in your sewer hose to prevent sewer smells from traveling back up into your tanks/rv?

Welcome to the forum.

Now enjoy repeated answering of your question, with the same response. I might as well add mine....

As others have said: "WHY" :h

The drain pipes in your house don't have "P" traps in them. Each sink, toilet, shower, drain, etc... all have their own traps. The entire system is vented.

Your RV is a mini-house.

The only time you should get a smell from a closed system is when you connect/disconnect from the campground (CG) sewer system. If you can figure out how to eliminate that....you'll be a billionaire by months end :B
