I also tow my TM so that the frame is parallel to the ground.

As far as leveling when setting up, I glued a bubble level to the lower exterior wall of the TM, which is fixed in relation to the frame and does not move like the shells. It is glued in a place which is visible through one of the shell windows when the TM is closed. I actually used the curb side window that is at the back when the shells are down. This measures front/back leveling.

For side-to-side leveling, I glued another level to the bumper.

This way, I can level the TM prior to setting up the shells, which I think is critical. Works perfect every time.
