Our '09 Silverback is now 5 yrs young....and going strong. Very few issues, all pretty minor. CC customer service is second to None..they are great. We are members of the CCRV Owners club - and know a lot of creekers.....many have owned 2 or 3 units.....
Trailer is currently in for normal maintenance (brakes, rotors, propane leak check, A/C cleaning)...the only thing wrong is a very hard to operate galley dump valve....
I think you will do well with CC Silverback....a solid mid-range unit.
