# 2016 Airstream Interstate Grand Tour wardrobe EXT Professionally Upgraded Off-Grid Ready

If you're looking for one of the most capable and extensively upgraded Airstream Interstates available, this is it.
Over the past two years I've invested well over **$30,000** upgrading this coach with premium components, focusing on reliability, off-grid capability, comfort, and ease of travel. Every major upgrade was professionally installed and designed to work together.
This Interstate has been meticulously maintained and has been completely reliable. Last year I completed an extended cross-country trip from Florida to the northern United States, across to the West Coast, and back home without a single issue. It comfortably cruises at 75 mph all day and has been an absolute pleasure to travel in.
I'm only selling because I'm launching a new business and simply won't have the time to use it as it deserves.
