Having a Hard Time Finding the Right Size Microwave

[ScottandMoni]

We are ready to purchase a new microwave for our Argosy and I cannot seem to find a trim plate microwave that will fit the opening. We'd like the trim style microwave so it will bolt in securely but may not be able to find one the right size. For those that travel with a microwave without a secure trim plate how do you bolt down?

Thanks~
