Common (and encouraged) in Colorado:
If you really want a site, the best way to get one is to go there in your car around Wednesday anytime or Thursday morning and setup a beater tent along with an older cooler, some beater chairs and "setup camp."
By the way, this is NOT encouraged in actual NFS campgrounds. There you must OCCUPY the site. But out in the National Forest and BLM land (even on spaces that are marked), those rules don't apply.
Before the haters start hating, this is the method
encouraged by the rangers and sheriff's deputies in CO. A deputy is actually the person who instructed me how it's done.
Set the tent door facing away from the road, and setup your chairs facing the fire pit. I use some cheap "L"-shaped tent stakes to keep them from blowing over...or away. I put a couple heavy rocks in the cooler for the same reason.
I know you said 2 hours away. I've driven as far as an hour one way for this purpose, and I've never been disappointed. But beware: enough people employ this tactic that you're likely to be disappointed if you're showing up on Thursday evening.
If you get there and the beater tent is gone, that's the cost of doing business. Since literally anyone could have taken the tent, the fact that there are occupants on the site is not prima facie evidence that they took it and "stole your" site. You might politely ask, but since the stuff was technically "abandoned" you have no standing on which to make any claims. But with all that said, it's never happened to my stuff.
You say you work for a living? I get it. Presumably you are off work sometime on Wednesday or Thursday.
My beater tent is a somewhat substantial (and serviceable) Coleman 4-person dome tent. A little pup tent may not have the gravitas to hold down the site.
