Are you any good at welding? If not then you are better off to take it to the welding shop and get it professionaly done. I did mine and if need be I could find some pics....but all trailers are a bit different.
Have two options........unless someone has another suggestion.
One is the Lost Lemon Campground....the other...the Crowsnest Campground. Any one been to any of these and what have your experiences been?
You need to remove the existing regulator from the unit prior to hooking it up to your camper. If you dont you will hardly get any propane coming through and hence no heat. Best bet get another hose made up for the unit at a bbq/propane gas retailer. That way if you want to run from a bottle you just change hoses. Yes there is a quick connect adapter that you can get and then put on your hose.
