I replaced all of my LL cabooses with Microtrains trucks w/o couplers and body mounted the old style body mount MT unit.
But again, I notice these otherwise neat looking cabooses also look "Lionel" because of no window glass.
A little snip snip with some acetal plastic from a new dress shirt collar, glue on the inside of the caboose side with Walthers Goo, just a little and you add to the level of realism a lot.
