Nice score with the structural steel channels. ❤

Will the channel bend under the stresses from the trailing steering tire load as you go over bumps on the road? The channel seems to stick out a fair distance with no additional support, may be an idea to add addition depth to the channel on the steering tire load side. this can be done by adding a section under the channel from rear axle to location of the steering tire. This would add a concentrated point load at the rear axle on the channel, if you were to weld a lighter open web truss section under the channel and under the axle to transfer the loads further to the front this would solve the concentrated point loading. This would only be needed a couple of feet each side of the axle, then the additional section under the channel would help to carry the steering tire load. The Channel has limited load carrying ability on it's side.
