That's Morse the inventer not Morris the cat. The Man's name was Samuel Finley Breese Morse. No relation to Morris the Cat food shill. He invented what became the first international digital communications system. His technology is now a historical footnote but we can at least remember his name.

At five hundred gallons the water weighs 4150#. That leads me to the suspicion that the truck may well be over loaded. Am I wrong about that? With the empty weight of the tank and the weight of the pump, firefighters, hand tools and a couple of fifty pound back pack pumps they are pushing the...

So let me ask the straightforward question. What size vehicle would be the safe level for towing the lightest trailer that would safely carry an S250 size shelter. I have a half ton van that is nearing the end of it's service life. Since whatever I get will have to serve as my work and tow...
