Hope you checked your appliances before you bought.
Also, you may want to check the tires. Even though they will likely have lots of tread, if they are the originals, they are now 5 years old. The rubber on the tires gets hard with time, and if you have any cracking on them, then seriously consider replacing them before you go anywhere.
The other thing that age affects is the battery, whether it is used or not, so consider having that checked as well.
A 22 footer should be nice and light so that you can probably tow it with a light duty truck, or even an Astro or Safari van.
