Does a new manufactured home on permanent foundation need a shutoff within 30ft?

I am installing a new 2020 manufactured home on my land about 40' from a permanent underground 200A service meter-center/meter-main panel (Eaton MBE2040B200BTS). This panel currently only has 2 circuits in it: a 110V 20A utility outdoor GFCI circuit and a 30A 220V RV hookup. Both receptacles are installed on the same post as the panel and two ground rods are installed. The manufactured home comes equipped with a Siemens MB2040B1200G 200A indoor main panel with the neutral and ground busses disconnected. The manufactured home will be installed on a "permanent foundation" consisting of a concrete perimeter wall with a crawlspace.

Here's what I'm thinking: Add an Eaton BRS225 main lug kit to the outdoor meter-main panel and connect 4/0-4/0-2/0-4 Aluminum Mobile Home Feeder Cable(RHH/RHW-2) to the Siemens panel in the manufactured home. I'll use Schedule 80 conduit where the cable is inside the crawlspace and also where it drops from the Eaton Meter-Main panel. The rest of the run will be direct burial without conduit. I'll leave a 6in section of rebar sticking out of the top of the foundation wall and connected to the main horizontal rebar in the footer as a Ufer. I'll use a rebar rated connector to connect to bare #4Cu and run that to the ground bus bar in the Siemens panel.

Questions: Do I need an additional disconnect outside? Will my Ufer be all the grounding I need? Am I on the right track? Thanks!!

EDIT: Here are photos of the breakers in the manufactured home panel.
