First, LOL @ 2 years.
We embarked on a 14-month trip 12-months ago. By month 4 or so, we realized that we needed way more time to see everything we wanted and to spend more time at each destination.
Second, just realize that you're no longer camping. You're living in a camper. It's quite a different mindset.
Third, know that your camper isn't designed to be lived in. Little things will crop up- stupid stuff like you never thought of.. for instance, I've replaced 5 sets of drawer hardware in our bunkhouse and have fixed the bottoms of 2 different drawers that fell/broke out. BUT- it's worth it. We have a great time with it.
