If you have those couple weekends to shake things out, you should be good if you make sure to use everything. Even if you don't need it.
Stress the systems a tad to see if there are issues. Run the water, AC, heater, etc. Use the oven, stove, microwave, etc..
9 time out of 10, you won't have serious issues. The problem units get posted the most on the Internet. People who have had no issues, usually don't post about it. Think of how many problem posts there are vs how many units sold overall. It's really a small number.
Add to that, the reality that most issues can be lived with for a while. That means it won't ruin your trip.
That and a positive mind set, and you should have fun.
