1) You need to look at the output current rating (AMP) of this AC to 24dc adapter, this 24vdc adapter is a regulated switching power supply that will maintain 24vdc output up the maximum current rating and also has shutdown circuits if the over current draw is detect and also if the
output voltage goes up beyond 24vdc to protect the load (TV).
2) To use 12vdc to 24vdc DC-DC booster, it should have the following spec:
A) The output current rating should be at least 20% higher than the load requires to give its head room.
B) It must have regulated output that will maintain the 24vdc when the input (12vdc) will vary from 10vdc ~16vdc or higher since
your batteries will not maintain exact 12vdc all the time.
C) It must have good protection circuits that will protect it self from reverse polarity connections, shorted output protection, over voltage output protection.
D) It should provide AC ripple spec on the 24vdc output, it should be in the
milli-volt range (you will always get AC ripple riding on top of DC when you rectify the AC into DC).
These are the minimum requirement for your DC to DC booster, which you need to protect your TV and your motor home from burning down.
I hope I explain it OK to you.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
