Thank you all for the replies...
WesternRVParkOwner has brought up some very valid points in regards to the "foreign worker" situation which I kinda already knew. Which is why a lot of the workamper and other sites don't really fit for what I'm talking about.
But let's say me/you are friends and I am staying at your house. You are in the procedure of building a garage and I offer to assist. I don't want to be paid a nickle. Not one dime. But, I do kinda expect room and meals and probably a beer or two while helping you build your garage, etc. Is that still illegal? I completely understand I can't come to the U.S. to work but what defines "work"? Do I have to get paid to be considered 'work'?
What I'm looking at is something outside of the normal pay structure... Not volunteering for church's, not workamping for $$ but parking my bigazz RV in your driveway and doing some chores around the yard in return.
Being from Canada, we don't automatically revert to the 'what happens if / insurance ramifications / lawsuit" scenarios that most seem to jump to so quickly.. Or, maybe it's just THIS Canadian.
I guess what I need is a website to make friends on so I can just go visit them. :) Facebook here I come.......
