Oh man, what a trip, literaly! SO glad that while getting "tater home was a fiasco, it wasn't all that bad.
I had a 2 day trip from Los Angeles to central WA turn into 4 days (3 of them going 10 miles at a go in Oregon, with much under-car time between). Thankfully that car had a lot of sleeping room and I have a good sense of humor.
I suppose it's a bit late to bring up that most states have what they call a trip permit, allows you to drive an unregistered vehicle for a day or two just to get it from A to B. Was how I drove 'Tater, that had last been registered as a farm truck in '76, part of the way home w/o encurring the wrath of the state police.
Cool use for an old tanker tho, great idea.
