Noah,
I recommend the License. I didn't think I would progress through the hobby after gaining my Technician license in 2014, but I am now Extra Class and just about a 20 word per minute CW operator. I've even set-up a CW Key in my Mobile HF rig.
I don't like to "Rag Chew", and I'm not and "Old Fart" at 47, but have enjoyed having my mobile setup and like the safety and security of Comms when traveling.
I have an Icom 5100 mobile rig as my 2M / 70CM rig and a Yaesu FT-891 as my HF Mobile.
I use a Diamond RS730 Lip Mount and a short rubber whip for 2M / 70CM - I can hit repeaters up to about 40 miles away or more just with that setup and I get in the garage... For Travel I go with a taller antenna. No real additional grounding needed other than the lip mount for UHF/VHF... The short antenna would be great for trail use mobile - mobile, mobile - handheld....
For HF I use the Yaesu ATAS-120 Antenna on a Breedlove mount on my swing-out. HF is a different animal and I've installed about 15 grounding straps on the vehicle... I've talked mobile as far as Russia and Argentina on 100 Watts.
Many options and things to learn. Whatever decision you make its yours...
Current setup. Icom on the bottom...
