I agree your dealer should fix all those on a new rig...
But getting it done in less than a week will be challenging at best.
Most doesn't look serious - more fit and finish, but a couple concern me without knowing more details.
- Door of exterior kitchen not closing or locking right, seems to be crooked
Well - this is ok as long as the door is secure for travel...
- Water leaking from clean out hose area
Ummm.. what kind of 'water' is leaking? Fresh is no issue - but gray/black is a much bigger problem...
- Jack level shows error for right side jack
Does the jack function?? Pack some blocks for your trip if you have to level the manual way..
Of course not serious is the shower 'dribbling' - RV showers have a 'dribble mode' - usually a valve on the nozzle that lets you save water while allowing a trickle to maintain water temp.
Of course most RV showers are mediocre at best as far as flow - even with valve in right position... Swapping out for an Oxygenics is something I've done on both my RVs to date.
I'm heading to Florida this coming weekend as well... BUt coming from a bit further north than you... Safe travels!
