TRINDU
PBB Orphan
I'm going to build my next bumper pull and I'm torn between 5" 9lb channel or 5x3 x .1875 tube for frame and tongue. Thought about i-beam, but already have a heavy hauler and want to stay reasonably light.
Current idea is 20ft x 83", wrapped tongue, 4ft steel dove, 6k axles. I've quoted multiple brands and their all over $4k+, fuck that.
People keep trying to persuade me to channel because "the tube will rot inside out". Yet I have 70s scout frame and 80s Toyotas that dont have a spec of rust. I figured square tube would be easiest to work with and stay rigid. Instead of having to notch ever mount or crossmember with channel
Engineer friend told me to look at point burden stress tables, but that's little bit above my redneck paygrade.
