I'm renting a camper van for a week during my upcoming break and would love tips on how to know if a spot is okay to park in overnight. Whether off a main road or on BLM land, is there a resource to help with this?
well, that narrows it down, lol! This might help, caltopo.com has a layer depicting public lands, including BLM, however I'm not sure if that layer is with a free or a 'premium' account
I don't know a lot about VanLife, but I do know that Cabela's and Bass Pro Shops do welcome covert car and van campers on the parking lots to stay the night.
I have not used them myself yet but there are apps that share this kind of info for RVers. Just search for " app for free RV overnight camping" or similar. Generally you can dispersed primitive camp in National Forests and on BLM land for free for a limited period but the rules vary from unit to unit and may have local restrictions so need to check the local rules. The NFS web sites have some information including how to contact the local office.
No annoying app, or ads. Easy to use. Dated entries give current beta. Pictures. Descriptions clear on what equipment (RV, etc) fits, road conditions, limitations.
rvdump.com is useful to bookmark too.
