Communications when there is no cell service

So in a earlier post I said that I was going to add ham and cb communications to my fifth wheel for when we cannot get cell service, we have 2 BaoFeng UV-82 handheld radios for use in a 4X4 club we will use these till I get a mobile unit. The BaoFeng operates at 136 - 174MHz & 400 - 520MHz and on 25KHz (wide band)12.5KHz (narrow band)and they are programmed with local and state club frequencies so in Montana & Wyoming I should be able to reach out and touch someone if needed. I added a Nagoya 19" magnetic roof top antenna on the trailer it sits on a steel plate secured to the roof so the wind won't knock it off and when in motion I will take it down and it will attach to a steel plate mounted to the ladder. I bored a 3/4 hole through the trailers rear wall and into a overhead cabinet and sealed the hole, the cable will stay in the cabinet till needed.
