Aux battery mate, you want the power from the solar to top up that battery.

Yep I agree definitely the auxiliary battery , I ran mine on the crank side of the dual battery solenoid and killed the crank battery , I do have panels permanently mounted though .

The 747
I connect mine to my cranking battery, that way both batteries keep fully charged.

Would be ok to connect to the crank if it's a temporary thing but if you have a hard mounted panel I'd go aux battery , I do have a switch to connect both sides if needed for winching or I have a flat crank battery and I do have two gel cel auxiliaries and the system now works fine .

Depends on the Solar Panel Reg, the Batteries and the Vehicle BMS (if any) and if it is solely for camping... without knowing that info Aux is probably the best bet.
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.
