I guess I should have did a "Paul Harvey's.....And the rest of the story" LMAO...... We have a feed conveyor underneath my grizzly, hence why it tapers to the center. Only move it if I want to, not because I have to. It is 2 3/8" oil pipe at 6" space, right around 7' on high side that tapers down to 3', using 8' pipes. Been like a wet dream for 5 years of use. Granted I'm not putting car sized granite rocks over it, but I guess the largest has been near a 3 footer, but average 1.5 to 2' rocks. An ounce of brains goes a long ways. Just cuz it's 7' in the back, don't mean I dump my loads all at 10'. I'm not abusive to it, but I don't baby it neither. Like everything, there is no one answer that fits all applications. How big of rock you are putting across will determine thickness of the bars to be used, how big of rock you want to be grizzlied off will determine how far you want your bars spaced...and so on and so forth. A big one too, who will be dumping across the grizzly...if using hired help-make it as thick of bars and heavy duty as possible, normally they don't care, cuz they will still be getting paid to fix what's broken.
