Phantom/hidden battery drain/draw?
Ever since returning from our last camping trip, the battery refuses to hold a charge. I have checked all the lights, switches, hidden lights, etc. and everything is off. I have just kept the TT plugg...

As others have said, you may just have a dead battery.
However, I think it's a wise decision with any kind of RV or travel trailer to install a battery disconnect switch at the battery. This way you can be absolutely certain no parasitic load is draining your battery when you are not using the RV.
When we first got our RV, the engine battery would go dead in between usages. Now the battery was shot, too (probably from being discharged so badly) but the engine computer, radio, and who knows what else were constantly draining the battery, so I installed kill switches on both the vehicle and coach batteries.
My RV was so old it did not have a hard-wired CO/Propane detector, but I quickly added one, so that would be an "always on" load on my coach if it were not for the kill switch. Likewise the TV is always in "standby mode" so it is drawing a little power whenever it is plugged in to 12V.
Battery disconnect switches give you peace of mind that your batteries are not wasting away while your RV is in storage.
