Full-timer taking Airstream into Mexico - Help!

I also am a full-timer. Almost everything I own is in my coach. That includes enough tools to outfit a woodshop and all kinds of electronics, including O-scopes and meters. When I first got my 10 year permit (in 2005) I attached a list of every major piece of equipment in the coach (2 pages) to the form and no one even looked at it. In the last 9 years no inspection station has ever said a word about all that equipment.

Now if it was new in-the-box, I'm sure it would be another story altogether.
