Mickey48,
Probably not. There are parasitic items in the trailer that consume very small amounts of electricity all the time. Radio or TV, Smoke and CO detector are two of them.
You will find that the battery will only last about two weeks before being discharged.
When leaving my trailer for extended periods without elec hookups, I used to just disconnect one of the battery cables from the battery. Easy to do and there is no question of whether the battery will be drawn down by "phantom" electrical items in the trailer.![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/smile.gif "smile")

The controller amps first power any house loads which can be significant and the difference will then charge the battery. Only a battery monitor with a shunt can determine battery charge, SOC etc

This is my battery monitor shunt and full battery disconnect switch. While the house batteries are AGM (with no corroding fumes) there are nearby flooded starting batteries. I spray the shunt and the connections with a battery protector.

Buy a Victron battery monitor. Several models to choose from. Get the lowest cost one.

You should be able to put a multimeter on the battery during the day and watch the voltage or look at your charge controller to see if its charging the battery.
As far as keeping the battery topped off while in storage - if you have a battery disconnect switch which will stop all power from going into the trailer and your charge controller is hooked up to the battery it should keep it charged and topped off - thats how my setup is
