As mentioned, you can upsize some, don't oversize to much.
I went from a 25K to a 30K with no regrets, warms up the trailer a bit faster.
Couple of things to consider, read the manufacturers installation manual, upsizing most likely WILL require adding at least ONE additional hot air duct. Manufacturers installation manual should tell you exactly how many hot air ducts will be required (and/or the total square inches of outlets) for the size of furnace you selected.
Upsizing also may require upgrading the 12V wire and fuse size from the fuse panel. Sometimes the bigger furnace will have a blower that draws more amperage than the original which may require you to upgrade the wire and fuse.
