Would you please include the year and model of your Rv when asking questions. It would help in the replies so they are appropriate for your particular Rv.
This can also be done by including your Rv info in your signature and/or on your user info link.
This is how to add a signature to your posts:
Near the top of the page in the black bar on the left, you will see--UserCP
Click on that. It's your control panel.
Scroll down a little and on the left side you will see-- Edit Signature.
Click on that and type in your year and model of your Rv and your name if you want to.
Remember to go to the bottom of the page and click on Save Signature.
