For many trailers, at least, an axle at the far end would tend to bend or otherwise damage the frame if it carries weight at all frequently. They are not designed to be supported by the extreme ends, but rather from the middle primarily. I'm sure there are a few exceptions that are relatively overbuilt; however most RVs are about as far from being overbuilt as they can get away with, speaking generally.
If the trailer has a good frame, lifting from the rear should transfer a substantial amount of weight to the tow vehicle. This is from experience .... once had to lift a 34’, 16000 pound 5er, approximately 4 1/2 to 5 feet from the rear....to lift it off of a 8” diameter steel post. Don’t ask! :o
