Bob, I replaced the main TV to a Samsung Smart TV. It has both tuners (ATSC and QAM). The 32" is available at Best Buy for about $175.00.
Another option is to buy a converter box that has both tuners.
Both options make it so that only 1 TV at a time can be used.
The next park that I am staying at has n encrypted cable box. They will let me borrow a box with a $50 security deposit.
