Well, maybe. There has been much discussion of those Suckee TVs on this forum. Do a search and read away.
We were in a couple of RV parks where our TVs didn't work because of a lack of a QAM tuner. So I switched out one of the TVs with a smart TV on a Black Friday special. Since then, we have been in a couple dozen RV parks and our remaining Suckee TV worked at every one.
Your results may vary....
May the trails always twist in your favor
May the tales always end in good light
May you have more friends than one campfire can hold
