I periodically check volunteer.gov to see what's out there. Just looked. Interesting pure volunteer opportunity to do from home is working on"The National Map" https://www.volunteer.gov/results.cfm?ID=13596
I plan to spend some time checking out all that map site has to offer.
Another Oregon position is in Welches which is at a day use area on the western slope of Mt. Hood. We stayed in Welches when we first fell in love with Oregon. You do clean bathrooms but you get your final full hook up site plus they pay $8.50 a day per couple and you work 4 days on then 3 days off together so you can use the money for gas to explore a gorgeous area. Or save the money and hike some amazing trails. Just watch out for the banana slugs. Those babies are BIG!
If you are thinking about camp hosting, check out volunteer.gov - you can put in the filter that you need an RV site (or housing for those that don't have an RV at the moment) and a state and even narrow by type of job. John and I would prefer "interpretive host" to camp host just because we like to learn and teach but I expect we'll be doing everything once we get into it.
