A lot of people build “portable” HF stations that they can set up quickly. Low power (QRP) stations are very popular. I’m doing this because putting an HF antenna on your vehicle is pretty daunting. But you can do 10-12 meters pretty easily with an old CB antenna. The problem is the sunspot cycle is bad right now and 10-12 meters isn’t very useful at the moment.
Take a look at a Yaesu FT-818 or the new Icom IC-F705. One of those with a very basic dipole wire antenna or even a small end fed half wave will work very well when you stop for the day and set up camp.
