lcd and led both use the same display technology: an lcd panel. the difference is in the way the panels are back-lit. the lcd uses fluorescent tubes around the edge of the panel, while an led set uses rows of leds around the edges or a grid of leds behind the panel. the advantages of led sets are lower power consumption, cooler-running sets, thinner overall, and lighter.
get the led.

LED is a LCD. Led is the form of back-lighting. Ones advertised as LCD are probably the older florescent tube back-light. Most new Tv's are LED edge lit ( Led's around the frame edge of the picture) There are also full back-lit Led's that are expensive that dim sections to provide better contrast .. Blacks. But can be price prohibitive.
Get the LED lit LCD (Marketers drop the LCD name normally) its Lighter and the LED's have the potential to last longer.

All of them can handle temp extremes ( they are shipped in trucks and left in trailers unheated/ cooled for weeks at a time) unless you try to turn them on in those extremes They need to be at a reasonable room temp to use.
My post's are my opinion The advice, comments etc are free and worth what you paid
Measure the maximum overall width and height that will fit in the space provided. The new set doesn't have to fit inside the hole the old one is in. If you are replacing an over-dash TV all you need is enough space to open any cabinet doors to the side(s) of the potential new set. Get the biggest set you can afford and fit.
Find a set with front speakers. There are models for the home that to reduce visible framing the manufacture moved the speakers to the rear. An extra HDMI input on the side is handy for connecting cameras, games or as I do the cable TV DVR from the home.
Don't over engineer the new mount you will need. I mounted my set using to 1/8" x 1" aluminum stock. I also added thick, wide weather strip anywhere the set contacted the original cabinet to eliminate any noise or squeaks when going down the road. If you can come up with a secure hinged mount that will give to access to the area behind, even better.
My mount. There are actually two mounts when I was finished. This image only shows one.
Weather strip around edge. I'm thinking of adding 1000 watt power inverter to fill the space. Notice the heave aluminim framing the coach builder used to hold the old TV in place. Made mounting very easy for me.
New TV, Vizio 32 inch. Has WiFI that I connect to my smart phone and stream video. There is an inch of clearance between the edges of the TV and the left and right cabinet doors.
Original. Now in the spare bedroom until the cable service stops analog service.
