I forgot to mention the screwdriver antenna. It can be mounted permanently and can be tuned for multiple bands. It’s what a lot of guys install on their vehicles and use to make mobile HF contacts. You could install one on your truck or camper and wouldn’t have to put up an antenna. That’s probably the best solution if you’re not into hanging an antenna at every new campsite.
On another note, I’m waiting to see how portable Elon Musk’s satellite internet will be. It could provide communication wherever you can see the sky.
