Sorry to take so long to get back to you on the microwave dimensions. I have the RV stored away from home since it is too tall to get into the garage. The microwave is 18.25" wide by 9" high by 11.5" deep. The brand is Samsung but I can't see the model number without removing it. It is very basic, just enter the time....no preset buttons like "popcorn" or "thaw".
tip: since the case is metal it makes a great place to store my long knives (or other metal objects) using small rare earth magnets which are extremely strong, won't break loose during travel. You can also buy them with a hole in the center so you can mount them in wood. Great little things to have around.
I haven't crawled underneath yet but will tomorrow. I have it home overnight to plug it in and hook up my satellite dish and receiver to make sure they work before I take off later this week for a maiden voyage to get myself broken in. It is difficult for me to get down on the ground to check it out from underneath but I really want to understand what is there so I will do it tomorrow. I will also get on a ladder and check out what is on the roof.
My rear view camera doesn't work because the video wire from the camera to the monitor doesn't come all, it is unplugged and I can't find the other end. Have you had any experience with wireless rear view cameras that you want to share?
I can't thank you enough for your help. If there is anything I can help you with don't hesitate to ask.
