TM cover for 3023

Has anyone bought a ready fit cover for a Class A, C, or Travel  Trailer and use it on their TM?  I see that the pop-up camper covers are too small.  It looks like from the Camper World catalog that they are too narrow and not long enough for the 3023.  They maybe long enough for other TM, however.  I was thinking of buying the best fitting ready made cover and cutting off one third of the bottom all the way around.  I could have the bottom finished somewhere.
