If you have the "RV Radio" installed, rather than Ford OEM, that might pull the battery down really quick.
I am on my second starting battery, about ready for a third (this one is 60 months into its 36 month warranty).
When new and fully charged, the size 65 starting battery has for me been good for 2-3 months of storage and still hold charge for starting. That's with only phantom loads from the engine control module and stair controller, radio is disconnected (actually switched to house batteries, which are then disconnected). But longer storage will pull it down to fully discharged, less than 10 volts, which is damaging, as the plates sulfate.
A decent starting battery is good for maybe 10 deep discharge cycles. It can be destroyed by one really deep discharge, I've seen an interior light do that, just the kind of load it takes to pull one down to no measurable voltage.
The other problem with the way we use these starting batteries, is the way they get charged after a deep discharge: they get blasted by the alternator, which is designed to put on a finishing charge at high voltage, after the small discharge from starting.
If we want that starting battery to last, we need to put it away fully charged, and put it on a maintenance charger or positively disconnect it from all loads.
In your case, whether you wiped it out early, or you just got a bad battery (it happens) you need to take it back and get a replacement. Most likely you got it with a warranty that covers 100% at this stage of its life cycle.
