If your going to use the crank up antenna I used the laird as I do now on my 5th wheel. I mounted it with the brackets that come in the kit but had to add an extension to get around the AM/FM antenna. I followed the same "entry" as the TV antenna but spent way too much time trying to fish it down the wall. In the end it looked nice, let me crank up antenna and was on air, but had to use RG58 and had about 30'. It also knocked out the TV apparently only when the wife was watching . I had it on the repeater first then ended up moving it to my midland radio as a "base" in the unit. When we got the MH I didn't want to deal with all of the wire stuff which is why i got the FG4500. Mounted on the motorhome with the cable run down the ladder along frame rail to the compartment made it simple and effective. Its about an 1" taller than my vent covers and most of the time have left it in place even while traveling. I did remove it originally thinking it would get hit but so far its been fine. In reality if it gets hit I already hit my vents and other stuff on the roof. But again its a 2 minute job to remove it. Inside the MH I have the Midland 275 on the dash hooked to a NMO mount in the center of the MH. I removed the factory AM/FM antenna and put a thick mount NMO with a 12" stainless disk under it. It works perfect. 99% of the time its just talking to the repeater anyway but when I'm traveling down the highway its nice. Depending on your camper your roof will be rubber coated or fiberglass. Neither will give you any ground plane so you will need to add it. Also its a sandwiched roof inside layer, foam, outside so trying to mount an antenna on it is challenging. You could just screw a piece of steel on over the rubber and use a mag mount but that leads to other issues. Getting a cheap base antenna is probably the best bet without alot of work. IF you have solar the other option may be to use a L style mount on the Solar mounts. I did this on my fathers MH but he only uses it to talk to me when we are traveling.
