We are new to Rving---help with Aladdin System & Weldex

Thank you Doug. The Roadmaster chassis was mfg'd in June 2005. The coach was mfg'd July 2005. S/N 060119713883301 157305 - Not sure if this is helpful information. It has Aladdin Video Coach System and a Weldex monitor. I guess it could have been installed by previous owner(s). We are 3rd owner. Thanks for what you sent, I have printed those pages for reference right now. We do have an owner's manual for 2006 model. I will keep this manual for reference. Thanks again
