First off, welcome to iRV2!
Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are here
Re: Mirror bolts to coach. If Ramco made your mirrors, you will need to remove the mirror arms. This will allow you to remove the plastic cover over the bolts that attach the arms to the coach. If Ramco made the mirrors, you should see their name on the plastic "button" that covers the bolt on the underside of the mirror arm at the coach (not the mirror) end. Pointers on removing the mirror arms are here
. A link to Ramco's Web site is here
If Velvac made your mirrors, you can look on their Web site (link here
) for information.
