Seems like everyone else is busy... I can't speak to exactly where it is, but, all models of travel trailers made in the last 5-10 years, that I know of, have battery disconnect switches. A lot of manufacturers get pretty creative with where they tuck them.
Look for a silver knob (looks like an old fashioned choke knob if you remember those) somewhere near the entrance door or in a storage bay (in the '08 210WBS it is in the front pass-through compartment). Our friend's '11 244RBS has a "main control panel, right near the floor at the front entry door that contains all of his switches (pump, slide, awning, HW heater, etc) and his is located on that panel. {As an aside, I wonder what silly engineer decided that all the control switches should be little, tiny switches located at floor level? Old farts like us (Bob and I) have to lay on our stomachs or go outside and peer through the open door to read and use the darn things...
} On most of the FunFinders, pulling it out connects the battery, while pushing it in disconnects the battery (backwards to my thinking, but, that's the way they work). I think by '10, CruiserRV had moved most of them inside the trailer, I had to make a shield for around mine, in the storage compartment, to keep stuff from sliding against the knob and pushing it in, disconnecting my battery...
