The 2011 Coachmen Catalina 24FBS seems to have come with 14" tires so the 15" must already be an upgrade (or factory option). The smallest 15" GY Marathon LRD is 225/75R15 which will be a bit bigger than the 205/75 you have so check that you have enough clearance for tires that are a bit over 1" larger diameter.
They do look good though!
