The battery box was designed, crafted, upholstered, and mounted inside my tow vehicle by friends Bill and Kathy. See November 2011 blog entries for more about this custom box.

What is the BLT?
BLT is what I consider the Best Little Trailer, a 2011 17-foot Casita Liberty Deluxe which is the full-time home for me and my crew.
What is the PTV?
The PTV is the Perfect Tow Vehicle. It's a 2005 Chevy Express van with a V-8, 5.3 liter engine and equipped with a 200-watt solar panel on the roof and two AGM batteries inside.Find what you’re looking for!

Hi Sue, Do these maint. free batteries have to be vented they don’t appear to have vent caps on them? Also do the people and or doggies suffer from the fumes?
Hi, Joe,
I don’t know why your comment didn’t appear on my admin. page so I would have seen it and answered your questions sooner. Sorry about that.
These are sealed AGM batteries, no fumes to bother the crew. The battery box is vented so heat doesn’t build up.
