Hi Scott and welcome to TCA. To answer your question, there are no downsides putting this on a one-ton. You’ll have payload (lots of it) to spare, which is what you want when buying a truck camper. The Livin Lite 6.8 is a great truck camper. Love the aluminum build and storage. The only thing I don’t like about it is the small fresh water holding tank, 13 gallons isn’t very much.
