Battery Box Extension Plans

I just posted a new ad on Airstream Classifieds.

I have designed and installed a battery box extension for my Airstream. My modification does several things that accommodate both larger (like Group 27) and taller (like 6V) batteries. It removes the fwd flange and attaches the hinge differently to increase the opening by 1”; and it adds 2 ½ inches in height. In addition to accommodating taller batteries, the additional height is helpful to house a shunt and additional wiring for a battery monitor like the Trimetric (an important dry camping item).

Two pictures are attached of the finished mod. The plans are for sale for only $10 and you can pay via PayPal and I'll email them to you. The plans are quality, dimensioned drawings (I'm a design engineer) which I sent to a sheet metal shop for fabrication (found via Or you can fab them yourself if you are handy and have some sheet metal tools.

Here's the thread:
You can contact us by filling in the form on the right hand column of the ad listing:
