For lotsa reasons I have always wanted to have a 100 pound bottle of propane around in case of emergency. I finally pulled the trigger the other day after getting 20 lb & 30 lb bottles refilled.
The biggest challenge from a DIY viewpoint is transporting the charged bottle in a vertical position. The Internet was strangely silent on good ways to do this. So here is what I think is a good way.
The base needs to be constrained just like the top. After looking at my truck, I decided the tank needed to sit forward of the front of the front of the bed just to get a good angle on the tie-down straps. Don't beat me up on the big whomp on the front of the bed - I had help...
