Thanks for the replies!
This is what I have in the power compartment, it's an Iota DLS-30
I only have one battery on the trailer, it's a deep cycle
It has a Onan Ultraquiet 4000 Genset
Hoping the battery and inverter can run the tv/sat

The DLS-30 is a converter/charger not an inverter. The DLS-30 charges your battery and supplies 12 volt DC to your RV.
Best Buy sells Insignia brand TVs which is their store brand. They have some models up to 32" that run on 12 volts. When looking at TVs, view the picture from an angle to see if the picture quality drops off.
Since you are planning also to use a satellite receiver which will need 120 volt AC, you might as well buy an inverter. I have used cheap MSW(Modified Sine Wave) inverters in the past with no problems. You can pay more for a PSW(Pure Sine Wave) inverter if you want to be 100% sure of having no problems. A 300 watt inverter would be more than enough to power your TV and sat receiver. It would be best to hard wire the inverter as close to your battery as possible. The cigarette lighter socket is a very poor power connector. Most inverters have a fan and some can be very annoying. The fan on my inverter only comes on when the temperature rises to a certain level. It only comes on when under heavy load.
