Most are hung from a bracket and screwed through the bridge cabinet. Open the cabinet and look for 2 screws going down to the MW. Some are also screwed through the grill into the bracket. You'll have to do a little research. This is a very heavy item that will need 2 people and under support to keep from falling on the range.

No screws in bridge because the bridge is a spice area because this is mobile home

Then it is probably screwed through the bracket from the front. Remove the front grill and look for long screws that will bolt the MW to the bracket. Is your wall construction 1X4 or 2X4? See any carriage bolts on the outside wall?
