We have one of the smaller Coby AM/FM/DVD/TV units, and it has its good and bad points.
On the good side, it fits perfectly under our Scamp
kitchen cabinets, tucks neatly away when not in use, runs on 12v (a big plus), has low power consumption (0.7A with the DVD player running), and can make a rainy night more entertaining when you just want to park your brain in neutral.
On the not-so-good side, you need an external antenna to get either a TV or radio signal through a Scamp's Reflectix insulation (something it has in common with most under-counter units, and we already have a 1.25" 3-piece PVC mast and "batwing" HDTV antenna for when we use the TV . . . but I still need to add a permanent-mount AM/FM antenna outside), and, even then, many of the places we boondock don't have broadcast TV. And I sure wish Coby had your larger screen unit when I shopping for ours; a 10.1" screen is just a bit to small for my tastes.
Here's a tip for you: drill a few extra holes when you mount your unit and add a nylon webbing strap to keep your TV screen closed. I also kept the thin foam screen-protector sheet from the original packing, trimmed ot to the exact-fit size and used a spray adhesive to attach it to the underside of the radio cabinet to protect the screen while our trailer is on the move.
