Re: Stress testing a Rhino

Total weight was actually about 130 lbs. We ran out of steel tubes after that... We were pleasantly surprised by how solid the rhinos were. (Surprised is a little strong, I generally trust AndyMark to make quality products, but it was still nice to see.)

For anyone wondering, they're tied together with 4 bars of 1010 80/20 extruded aluminum, which is heavier than the REV Extrusion recommended by AndyMark. We already had the 1010 in the shop, REV Extrusion was sold out, and we didn't mind a little extra weight to have fewer worries about how solid base of the chassis was.

The sides of the Rhinos are 3/16" aluminum plate with supports every few inches and are incredibly solid, so we are not too worried about T-boning. (That said, we are planning on having full length bumpers and external frame rails to help protect them as well.)
