Collette, in response to your questions:
1- When the tongue has been removed, the trailer sits on its front jacks, or in my case on two cinderblocks padded with a 2x6 board.  Be sure that the heighth of these blocks is identical as the trailer will be in a twist and might cause the frame to warp over a period of time.

2- On the most recent models of the TrialManor Trailers, the battery (ies) are installed in a compartment at the rear of the trailer.  On mine (1999) the batteries originally sat on the tongue.  Based on the drawing, you will see they are now resting in a cage that is below the level of the tongue.
