I got lucky. Went down to the local gas station with my buddy and one of the dudes filled them up. So I should be good for quite a while. Can't imagine I'll use propane that fast, so at lest for maybe 6 months to a year I'm good.
Just one less thing I have to worry about. The less for me is better. Getting an older camper, then getting it setup and making sure that things work and don't leak has been quite a stress for me. We are using it this weekend for tonight only. Nice little test run not that far away to spend some time with her parents. Everything seems good so far. Kitchen faucet needs to be rebuilt and a couple of cracks in the roof when I washed it, but nothing too out of hand.
