So if you are perusing range, SWR is the wrong rabbit to chance. The efficiency of the antenna is where to look.
So, with a good SWR, you won't damage the radio. But to get good range, the cable and antenna need to be doing a good job of getting the signal in the wire into the air. The best way to test this is by measuring field strength - which can be coarsely done with just another receiver - like your handheld radio.
So using your theory, we can just stick a coat hanger in the back of the cb radio and we're as good as we can get when it comes to transmissions???? Maybe move it to the roof for a better view?
I'm being sarcastic I know but, I don't think your theory is accurate.

Always another project to get things like you want them. I used to get to listen to all of the local POLICE/RESCUE SQUAD frequencies but most of them in VIRGINIA now has gone to the digital mode... All I hear now is a loud BRRRRR when they transmit... geesch... Those scanners cost $400-$500 so I guess I won't be doing that anymore...

I don't think anyone is going to install a 102" whip on a Motorhome, let alone build a mount to hold it that won't tear off the roof. It's just 11 mtrs

lack of proper ground is your problem. back in the old days I had that problem and a friend of mine cleaned up the ground and I blew the doors off the truck with power and distance. I know you said you had the no ground model of antenna but that is still your problem
