Would of loved to see that. Real ones take a little stronger trailer. Talk about bombs, we in New Hampshire are going through a crisis over a new pipeline, destroy the ecosystem, make our children irresponsible, all the goats will abort etc, and meanwhile they have a local distribution pipeline in Keene that uses a mixture of propane trucked in, and air. Now it gives me the warm fuzzies to follow a tanker truck of propane, or watch a half dozen tank cars go by on the railroad and think about our friendly peaceful moslem brothers and their sometimes playful games. Toy bomb, no problem, couple hundred tons of propane moving at 50 mph, little bit thought provoking. USAF was playing around with enhanced boiling liquid explosions in the late 1950's and I saw a few things that scared the heck out of me, non atomic, but damn big and hot. A little c-4 and a 55 gal drum of gas is one thing, but replacing the gas with propane does some weird things as it vaporizes and burns.
I guess if you may have an abomb on your trailer, you could tow it with whatever you want. If I was a LEO and saw that on the road, I would put on my lights and retreat about 10 miles and call it in after my shift was over. I only saw one very small one go off in my life and that convinced me to never ever want to see a big one. Kind of like watching a tank fire a shell, buddy you don't ever want to make that man mad at you. Takes cover versus protection to a whole new level.
But officer, the guy at the surplus store said it was a fuel tank and it set up on those pointy things in back. He thought it still had fuel in it, had to load it with a big fork truck, and told me to be real careful on the bumps as it could spill. Mr Mojjhammad at the surplus center gave me a real good buy on it when he found out I lived in Washington DC and said to be sure to go right home with it as my trailer lights weren't working . "Sarcasm" I hope?
