Hi Sharon, welcome to the forum.

Congrats on your purchase.

You just want to make sure all systems are in good working order prior to leaving home. Tires are one of the costly items when you first buy a used MH, the ones on it may look perfect, but they may be very old. Have the date codes checked as well as the condition of them. If they are older than seven years you may have to change them. If a tire lets go on the highway it could destroy bodywork, holding tanks, etc.
There are interesting places in all of the states that you named. I live in So Cal and have traveled the whole state as well as Oregon and Washington. Western Canada is nice also. I've traveled to many places in your state also. My Brother In Law lives in Gooodyear, Az, so I've been there many times.
