Issues I have had with our 2014 37F:
Drawer in galley had slide rails out of parallel (fixed myself)
Outside Grab rail screws rusted (replaced with SS from Lowes)
Outside Compartment locks (3) key'd wrong (replaced by Winnebago)
Hotwater Heater on propane would not stay lit. (adjusted flame myself)
Towel ring missing in back bath (Winnebago sent one)
Plastic vents on drivers door window missing (they snap in)
Full wall slide topper billows in strong winds (spring tension?) on list
Leveling jacks "pop" (TBD) I have seen this is a known issue. Nuisance mostly.
Ipod connection not accessible (its on the rear of the InfoCenter)
Hate the Rand/Good Sam GPS (posted on another thread)
Had to connect antenna on back of Blu-Ray for FM.
As I said mostly minor.
Added sewer hose holder
Added Hooks to shower door for towels (command hooks, but used 2 part epoxy to hold them)
Added Fumoto Engine oil drain
Switched engine oil to full synthetic
Added Progressive Industries power monitor (added after transfer switch protects Shore and Gen power)
Added in-line water filter in wet bay (blue inline and 90 deg brass fittings with short hose)
Need to add Valve Stem extensions (anyone done them?)
