Welcome aboard! I, too, am a former FR owner. I hada Flagstaff TT and a Blue Ridge 5er. Loved them both. I had a few problems the first year with the Blue Ridge that had me fretting and snorting, but I had an awesome dealer who fixed everything. The second year I had zero problems with it. The only reason I sold it was my field of employment is a little uncertainthese days (coal power)and I didn't want to get caught with a camper payment and no job, so I sold it and bought an older Cruiser. So far, the Cruiser has been great for a 2007 model camper.
I hope you have great luck with your new unit. Hope you have a ball in your new rig! There are several guys on this forum that know their stuff when it comes to troubleshooting and repair, so you can probably work through most stuff on your own with their advice.
