Replace 1 damaged "D" load range tire with a new "E"?

Replace all 4 tires with E's , new trailers usually come with under rated tires because RV makers cut all the corners they can to cut costs and maxinize profits.
pay now or pay later when one of the D's fail and cause a lot of damage. My traier came with C's and had 2 blowouts in one month, replaced with D's.
