I am going to assume that you want a 12 Volt DC Digital TV for your Conversion Van. Amazon.com has a good selection of 12 Volt Digital TVs. They also have a good selection of 12 Volt DVD Players. I am sure that one of these 12 volt TVs and 12 volt DVD Players will fit your needs.
I also have another suggestion for you. You might want to look into buying a 12 Volt Inverter for your van. An inverter takes the 12 Volt DC current from your Van's battery and turns it into 120 Volt AC power. Depending on the power inverter you buy; installing it can be as simple as plugging it into the cigarette lighter. Let's say you are going to be running an LCD TV and a DVD player. LCD TVs depending on screen size use 75 to 270 watts of power; a DVD player uses around 35 Watts of power. So a 400 Watt Inverter would be perfect for your needs. Again Amazon.com has an excellent selection of highly rated and well priced 400 Watt Inverters.
Using an inverter also gives you the flexibility of plugging other items in such as laptop computers, an Xbox Game System or a Blender to make Margaritas :-) An inverter will also give you a larger selection of LCD TVs and DVD Players to choose from.
You will notice that I only recommend using an LCD TV in an RV or Van. Read the answer to this question to find out why I only recommend LCDs. Should I Put A Plasma or LCD TV In My RV?

It seems to me that if you take power from your 12v RV battery pack, convert it to 110v ac for the input on a regular TV, then internally the TV converts it back to DC .... well there have got to be measurable losses in power plus it seem kinda silly when the doggone electronics all run on DC anyway.
Please comment.
Comment from RVing Al Yes a 12 volt TV will actually use less power, but by using an inverter it will give you a larger selection of TVs, DVD Players, etc. to choose from. There are far fewer TVs, DVD Players, etc. commercially available that are designed to run directly off of a 12 volt DC power source.
