OP: Should be able to find a generic remote that will operate the TV. Should be able to find manual for TV online. What is brand of TV? Any name on booster power supply?
Check the for 12 volts DC to power supply for booster.
There is some stations that still broadcast over the air. Not many networks!
Call Forest River for them to identify antenna.
Chances are the TV is Furion, Jensen or a few other low quality RV brand TVs. Most of those off brand RV TVs will be made in China and will have some common chassis which a universal infrared remote may have a code for a different brand that will work.
One of the major keys to digital OTA broadcasts is they use a "virtual" channel assignment now days. This means the channel number of the station may or in most cases is not the old legacy analog channel.
With this new virtual channel setup, one must rescan the TV tuner each time they move to a new town/city even if it is only 50 miles away.
As far as "some stations" broadcasting, no stations were removed from broadcasting, they did not go bankrupt or fail or quit broadcasting, they are still there.
What did happen is digital broadcasting does not transmit as far with the original power level and antenna systems. Many stations ended up losing broadcast area coverage, some petitioned FCC for increased power, antenna height and higher gain antennas. For some it required adding additional "translator" (translators act like a repeater and rebroadcast the stations signals on a different frequency) station licenses and new remote translator locations to claw back the lost coverage.
Digital broadcasting via ATSC (the digital TV standard now used) has a lot of flaws, local RF noise severely impacts the reception, rain, snow, trees all affect the distance and then with many more UHF frequencies available than VHF really impacts the distance. UHF is strictly "line of sight", doesn't bend with the Earths curvature, signal will skip over deep valleys between hills and buildings, trees or other solid obstacles simply block it..
