If you will be operating primarily off the road you can take just about anything. As previously stated, just about anywhere you will find a gravel pad. If you plan on sleeping at the road every night, no need to limit yourself to a one man tent unless you are tight on space. Just make sure you bring one that can withstand heavy winds at times and potentially some snow.
I typically bring a large heated tent that o can use as a base camp at the road and a smaller tent to spike out. Typically the ground out on the tundra is pretty wet and very uneven. There are few places out there you will find flat solid ground.
