Are you who I met today at Timberline Valley? If so, glad you decided to check us out &
I found the brochure for the 2007 Carriage on THIS
website. That's the closest you'll come to an "owner's manual" for your 5-r.
As to the appliances, they are fairly universal to all RV's. Especially with late model RV's, we've all got pretty much the same things manufactured for RV's by a few companies (i.e. a/c's, furnaces, hot water heaters, stoves, fridges, jacks, awnings, generators...etc). The Tiffin RV Network
has a wealth of information & links to download manuals for nearly all systems & appliances in your RV.
You can also check out the QUICK TIPS & EASY MODS
threads in the Newmar Owner's Forum. There's information there not just for Newmar RV's, but for RV's in general (winterizing, converting from CRT to LCD/LED TV's, basic info on RV electrical systems...etc).
And if there's anything you're specifically looking for, just ask. Someone here will know. We've got several members with Carriage RV's (diandtom & Lynnvt come to mind off the top of my head) - you're in good company.
