That looks in amazingly good condition. Good luck with it and please post more pictures.
1) Yes its attached. You must go to a supplier or have it delivered.don't know where in your area but some gas stations, camp grounds and places where they fill BBQ tanks.
2) No help
3) some times it takes a few seconds(10) to see the jacks coming down.
4) Could be the over flow. Check to see if the tank is full.
5) No help.
6) 2 heaters are drawing to many amps. You most likely only have 30 amps max. Maybe 20 amps. Try running just one see if that trips the breaker. If it doesn't plug the 2nd one in another outlet.
Hope this helps. I am sure you will get more responses. Good luck with your new adventure. I really like the chrome bumper.:C
