Get yourself one of THESE and tap into the wires coming from the dash radio to the speakers.

Perfect!

Almost... You still need a small amplifier for the wires from the TV to this A/B switch. The RCAs on the TV only put out line level audio. I have used one of these and it would be perfect for your installation since it has RCA ins and can handle down to a 4ohm load.

Cheap small digital amp

Are you saying the audio outs on the TV don't have enough power to drive the speakers? Why not?

They are not amplified, they are what are called line level outs. They are made to run to a stereo system for amplification.

Line Level

I see. That makes sense. So they aren't speaker outs per se, but more for like a soundbar (that has a built in amp - hence the plug) But would I get no sound or just poor sound? I was really hoping for a quick and dirty set up. The issue is that the flat screen has poor built in sound (as most do) and going down the road it can get hard to hear. Heance wanting more sound. I thought leveraging the existing speakers would be easy enough. Never thought I would have to amp them.

You would get a tiny little whisper of sound from the speakers that would (usually) not change with the volume control on the TV. Just add the little amp I linked to the mix and you should be quite happy with the results. The amp is very small, light and runs pretty cool so could be mounted about anywhere.

It will not reach the full power output it could with 4ohm speakers using the small included power supply but the output should be about the same as your average car stereo. One nice thing is that the power input is 12v so if you could tap into a 12v line and power it direct from your coach, you will get full power out of it.
