It looks like the tire could be moved a smidge to the driver's side (slightly limiting how far you can open the compartment door - but, it looks to be slightly limited in its present location anyway), and the swing-arm (grill stand) can be slightly moved to the passenger side. Even if the swing-arm protrudes slightly past the edge of the trailer, it will not be any more than your speakers/awning/patio light already do.
Our 233S has a similar rear compartment that has the hinges at the bottom of the compartment (causing it to open door-down). Curious why they wouldn't do the same with yours.
My guess is that it's a quality control issue at the factory. Not surprising, but easily remedied. We had a few minor such issues when we first got our camper, but I enjoy "playing" with it, so making a few "corrections" allowed me an opportunity to better know the unit.
Enjoy the new camper! :-)
