With my sportsmobile, being very conservative, normally only running the refrigerator and one light at a time I only get 1 day and one night and then I go below 12.00V. To conserve battery life, I tried to take out one of the two flourescent tubes from the light fixtures (since I don't need that much light) but then the other doesn't work. Any idea how to take one out? I know a lot has been written about battery life but I haven't been able to read a good answer (maybe it's an impossible subject). Running only a refrigerator and some lights, should I be able to get more than a day and a night of battery life? I have one of the lifeline monster 135 pounds $400+ batteries (I imagine they are standard).

Flourescent lights should only use up 1 amp if not less. LED's use even less. Certainly both of them use less then candenscent bulbs.
You might want to take a look at getting something like a LINK 10 or something that tells you how many amps your putting in and taking out; which the Link 10 does.
In my case, I had a similar problem that I solved by using the Link10 which told me that even though my battery was charged, and I was hooked up to shore power, the 12v devices where stealing the battery power on the backend.
So when I took off on Monday's, My Powerverter (Tripplite) thought I was fully charged as far as it was concerned (it when thru the charge cycles), but I wasn't really fully charged...
In my case, I also put in a cutoff switch (heavy duty) where all the 12v devices came together(12v fuse panel), and using the Link10(which showed me any amps being drawn) from the house battery..
For a good charge, I make sure all the 12V stuff is turned off.. and the Refrigerator switched to Shore power 110v..
In your case, I have no idea how old the battery is, but a Solar Panel "might" help augment what the refrigerator is drawing from the house battery.
