Looking at different Manufactures of the B+ over cab design , some are almost squared off while others have a better slanted back slope.
We've now test drove a Winnie, Coachmen, Forester C's and a few more can't recall the brands, but every single one had that over head creak, rattle kinda like plastic on plastic etching noise.
Just test drove 2017 Nexus Viper 27 B+ 4K miles on it,,,yep same thing creak , screatch, rattles.
Both our 2000 FW and 2005 5000 C's neither one had that noise.
Yes initial creak pulling out of a driveway/parking lot.
But not while just driving down the road on smooth pavement...
Is this a common thing or ?
