Minimal connect between Tablo and Roku stick

Long time home Tablo and roku stick user. However, want to use my roku stick and Tablo together in our RV while on the road where high speed Internet is not common. Was wondering if I could use an old router to connect the two devices inside the RV? This would be for OTA only since router would not be connected to the internet. Also, my guide subscription wouldn’t be available, but not sure if my scheduled dvr shows would work after the channel re-scan required at each new RV location. Thoughts everyone?

Tablo FAQs: Do I Need Internet to Use a Tablo OTA DVR?

free OTA, but you have to pay for internet access to view recorded content.
(not what you’re asking, you could use 3rd party apps to save shows for off-line viewing)
