Diane,
I hope you know how pleased we all are to boost you along. Some of these are hard won lessons.
Like Keys....
Never use the original keys. Keep that collection in side the unit where they will be safe.
Get two spares of door and what ever else you need to drive. (I our case, that is a set of three.)
Carry and use one set.
Hide one set that is accessible from outside. The reefer bay or under the engine hood. These should be protected from weather and vibration. (Wrap them in something.)
If you are as paranoid as I am, get a spare door key and drill a hole in it so you can put it behind the license plate and hold it with the license plate screw. OK, you will have to find a screwdriver or a Swiss army knife if you need it.
Yes, I am somewhat paranoid, but I am also OLD and paranoid.....
I hope you know that you will not be the only single lady on the road. We meet five or six in every traveling season. If you are on Facebook, look up Girls on the Go. We have some friends there.
Matt
