I know I only have a 21-footer and no covers, but I did find all the opening in a few hours lying on my back. One small step at a time, don't let the size of a job overwhelm you.
Two cans of foam, a few square feet of plastic air filter, four cans of rust reformer paint and I can sleep soundly. No minty smell, no mice.
The biggest entry point is that sidewall outside frig panel. Go out and look up, there are dozens of mouse sized holes that lead to warm air. Every stop you make with that frig going is an open invite.

I think anyone who gets them in their camper is concerned, but that is why I asked for help as it was my first time with this happening. I also have children, they are older but that is why I was in the camper every week vacume, washing and disinfecting, until i got rid of the problem, and the MINT Oil works. NO MICE!!!
