Do you have a vehicle mounting guide for a direct connection to the battery, pole mounted collector panel,in the instructions, and where is the recommended mounting location for the mppt charge controlle?

The MPPT charge controller is built into the junction box on the back of the solar panel, so there is no separate controller to install or mount.

For installation, simply:

1. Press the MODE button to select the appropriate battery type.
2. Connect the solar panel directly to the battery terminals.
3. Once the solar panel detects the battery, charging will automatically activate.

Therefore, there is no need to find a separate mounting location for the MPPT controller. The controller is already integrated into the solar panel.

Will this work with my Mighty Mule 371 gate opener

Yes, it works to charge your gate opener battery. Simply hook it up directly to battery terminals using cables provided, red to positive and black to negative. We had sold the solar panel to thousands of gate owners, and they are working great to keep gate battery topped off.
