I have a Yaesu 8800 in the truck, which can listen to 2 meter and 70CM simultaneously, but I'm not here for the commercial to sell Yaesu radios...

My experience over the past 10 years of traveling with a 2 meter rig in the truck is that it takes some thought to set up your radio for where you're going.
What I mean is that HAM radio isn't like CB where there are defined channels that you just choose at the flick of a knob and then talk.
Unless your talking radio to radio (simplex) on the 146.520 MHz, which is the National simplex frequency, supposedly monitored by most folks when traveling, you will need to know some details about the repeaters in the area AND be able to put that information into your radio either ahead of time or on the fly. While it's not impossible to put in the specifics for the repeater while you're moving, my radio requires attention to detail to get the repeater offset, DCS or tone code, and transmit frequency set right and still stay in my lane.
That said, once you get to a location and want to find someone on 2 meters, I use the "repeaterbook" app on my phone to find local repeaters. I have an apple, so I'm not sure if it's available for Android.
It geo locates you and shows you the specific settings for the OPEN repeaters that are close to you, showing the mileage from you to the repeater. This is Very handy to have. There are a couple of places on the Oregon Coast I go to, south of Newport, that are small islands of NO CELL service. If you or someone you love needs help, the HAM radio can get you in touch with someone that hopefully has a phone. Realize that simplex, without the aid of a repeater, your talk distance may be less than 10 miles depending on too many things to mention here. An RF engineer friend told me that when you buy an antenna, you only have half of a transmitter, and the radio IS NOT the other half, your
vehicle is, which makes up the ground plane. If you put a 2 meter or any other antenna on the roof or side of your RV, make sure it's grounded to the frame of the vehicle!
To add to this, I have my call sign on the back of my trailer with the frequency I'm monitoring while driving. My license plates have my call sign on them. I have talked with a total of 3 people while moving, and one of those guys was at a base station.
What am I saying here? Yes it's great to have a manner of communication while you're other wise out of cell service. But, don't expect that you will have 20 people waiting to converse with you while you're traveling. Admittedly, where I'm traveling, which is most often along the I-84 path between Idaho and the Oregon Coast, there are a lot of areas of very low density of people, let alone HAMS. Some cities have VERY active repeaters and you may have trouble getting to talk at all..
Either way, good luck and upgrade your license as soon as you can! SOrry for the long post. I'm sure you'll find several HAM's in your area that can help with set up on your RV.
