I have found an exact in-kind replacement for the door knob and deadbolt that were factory install on our '07. When I say exact, I mean the latches are the same 'drive-into-place' design, the knobs are an exact match in fit, finish, etc. The knobs could be used with the old latch, which I did with the dead bolt (changed out the main door knob latch as I had already pulled it to take to the store for dimension checks).
Replacing the door knob was necessary as our latch no longer fully retracted when opening from the outside. So the door would not open. Someone inside could turn the interior knob with full retraction of the latch. When I disassembled the outer knob I found the 'gear' in that knob was worn on one side so it would not rotate the latch assembly fully. AKA no fixing it.
So after a couple of years of trying to figure a way to pull the wing piece out (turnbuckle and hook worked this issue), I pulled the old knob and went to a Houston local Mobile Home and RV parts store. Sure enough, they sell a combo set with four keys. Sweet. Install took 10 minutes for both. No cutting, no drilling, no chiseling. Part number for combo set is 8-84286; manufacturer is J&D. Description on my invoice is 'Combo Lock Set - Silver 10-010(20).

Hope another link in the parts rolodex helps.
