brholt, ignore all the stupid comments about how silly rvia stickers are and how folks think their constitutional rights don’t require them to provide proof if it’s a requirement of the campground.
The voluminous blathering here really gets in the way of substance.
Handle it like this.
First call and ask them if the whatever number or a pic of your camper is good enough. But anonymously. That way if they’re douches aboot it, move to plan B and send them a pic of some RVIA number. Any one.
Chances are plan A will be fine.
If A or B don’t work, you could take a pic of a rvia number, print the pic cut it out the right size and stick it on with some clear bra.
If that don’t work, call them communists and camp somewhere else! Lol
