Dagwood, check out this battery box for the T-105s. I bought one for my two T-105s and they are perfect. I have a little fan that draws air from the box constantly while hooked to shore power.

Just got in my new Magnum invertor that I'm going to install(with some help I hope) this weekend. I also bought 4 T105 batts. I will have to make a battery box for them. I plan on going to Lowes Home Center and buying some kind of tool box or other box as close to the right size as I can for the 4 batts. Then using 2" flex hose to vent to the outside of the camper. All this will be in the basement of my 5er.
Question is: Will this work OK?? I will have a vent out, but do I need fresh air in the box?? Or am I making this too complicated??
