How large an inverter are you installing that it can't stay above the floor
line? If you need to drill to the outside just use a good sealer or paint to
prevent corrosion at the connection. Stainless hardware will keep itself
from corroding but any exposed body steel will still rust. The inverter
should be matched to the battery size for a number of reasons. A group 41
battery will have trouble supporting anything above 400 watts for any length
of time.

Subject: Mounting an inverter.

I have a '91 Multivan with a secondary battery kit under the driver's side
seat. I want to mount an inverter behind the battery compartment (i.e.,
behind the driver's side jump seat). Due to the geometry of the inverter,
two of the mounting bolts can be installed inside the battery compartment,
but the other two need to be mounted below the depth of the battery
compartment. I assume that this would require the bolts to protrude into the
wheel well. Is this a crazy thing to do? I was thinking that caulking would
be a necessity, but how many other considerations are there? Stainless nuts,
bolts & washers? Should I spray the area in undercoating after installation?
I have a great love for this van and am hesitant doing things that might
introduce corrosion. If you need pictures I can send you an idea of my
proposed installation location.

Thanks in advance for any ideas,

DW
