You do not need to own a Montana to join the MOC. If you own a Montana then joining the forum is one of the best ways to find out vital information about your rig. It certainly was for me.

We use a truxedo

To extend the slides with my Montana remote, I need to press two buttons in sequence. So it is unlikely that your remote is the culprit if it works like mine.

Looks like you will have to raise the fifth wheel. Either longer spring shackles or axles under the springs.

Either get a dually or scale back the size of your 5er by a considerable amount. Your truck is way too light for that RV.
