Trying to remove valances to repair blinds. I have a 2014 heartland big country. Cannot see how they are attached. Have tried everything except rip it off the wall...

Removing the valance is easy, typically using 2 or 3 wood screws with an S2 head. The biggest obstscle will be removing the blinds to access those screws. Depending on the type of blinds you have, they will be attached using the same type screw on a Day/Night shades or they could snap into a bracket like Slow-Rise roller blinds. If you can identify the specific blinds or manufacturer, Google them and look for installation instructions. They are usually in PDF format and long through them will show you the specific bracket used, how it is secured and where to locate the screws. If you have an electric screwdriver, use it to save your wrists and a 6" hex bit extension will make reaching those screws much easier.

On another note, I've replaced ALL the Day/Night strings on my toy hauler at one point or another and never needed to remove the valance,.
