Here is a link to the 2007 Dynasty brochure. It has a picture showing the structure of the chassis.
In this case it appears that the steel tubing may allow for a window on the passenger side but not the drivers side. I have a brochure for the 2007 Beaver Marque that is just the opposite, the passenger side has a cross member design while the drivers side is vertical.
But these are just general drawings and probably change based on the actual floor plan as to slide placement etc.
You may try and reach out the Monaco technical support but you'd need a specific make/model with the production number.
If you can find a rig close to you it might be worth a trip to see if you can determine if there is steel members that would prevent the installation of the window.
