well, between his network of engineering/design friends & the school's facilities, he has access to an impressive amount of expertise & equipment.
haven't heard from him since he left but i think the biggest handicap is lack of experience with real airstreams. for instance, understanding the way travel shakes up their insides.
since he wants to live in his full time, off the grid if possible AND pull it with his Audi wagon, that presents, uh, challenges. Like, where do the 12 deep-cycle batteries go?
But I was able to fill him in on some of the roadblocks to watch for & show him what works well & what doesn't on the various trailers.
He had good ideas for an awning with solar cells that would also collect rainwater (don't they all?!) ... and I thought my b'friend had a good idea of having awnings on each side of the trailer, one for solar & lounging, one for rainwater & storage -- maybe a carport?
anyway, it's always fun to hear someone else's ideas.
Of course I'm an elitist. Look around you.
