tha housings definately need some up grade

it takes over the weight of my pans to bow these housings which is flatening the mammoth tires unfilled . 1 major faill point is the axle extension at the screw area not much meat for plastic

and they just look to spinly not big loader like so like my mack , I'll be making new housings

steel I think will be overkill . There is plenty of room to fit everything needed
