Now that you brought up fuse sizes...my factory ones are likely too big since the conversion.
No more decompression controller and all of my lights are LED.
Maybe there is no need to downsize the fuse.....as the wire size has not changed - only the working current draw. I have 6 years and 10,000 miles and no electrical gremlins yet (provided you don't count my RYCA tail light getting soaked and damaged by a TN/NC rainstorm.
(You folks with RYCA style tail light should take them apart and seal the seams with RTV).
