Hello Michael,

The radio supplied is a so-so Samsung unit that is dark and hard to see when not powered up.

Yes one switch controls the kitchen and bedroom slides. They are hydraulic, and the front living room slides are electric (12 volt) cable slides.

The battery tray is 14 1/4 wide by 11 inches deep, so you can measure the batteries you bought to get an idea if they will fit.

There is no 12vdc to 110ac inverter, unless the previous owner installed one.

There is only one 12vdc outlet, as you found.

I don't believe there is a filter for the furnace, although it is not a bad idea.

Couple of other thoughts. You may want to consider the purchase a power conditioner, such as one from Progressive. This will protect your RV from dangerous voltage spikes and mis-wired pedestals. Also, inspect the drain hose on the kitchen sink. They have been known to come off the sink drain as the slide moves.

Take care,

Gary
