We are deeply committed to the concept of solo road trips here -- and in fact, my research shows that a significant & majority % of all solo roadtrippers out there are women. We have lots of tips about the best ways to do that.... That being said, I have some concerns about about anyone, male or female, combining a solo roadtrip with a household move. Are you familiar with those pack and drop containers? If it were me... I would use one of those services for your household goods and then take a considerably less stressful move across the country in your car. Here's one such company, (I'm not recommending this company -- I don't know anything about them -- strictly an example) What I do like about the service is that you pack your belongings as you wish, you lock the container and then let a professional driver haul it for you.
I think the chance of a theft of this nature is very remote. There are thousands of such trucks on the road in the summer months -- thefts of personal household property are pretty rare.I will be traveling with one cat, and have time to make the trip. My sons are fearful of my doing this, especially the thought of someone stealing my truck or it's contents while I am sleeping. I plan to use Penske because they seem the most reliable.
